The 7 Biggest Blunders You Don’t Want to Make Choosing a Shower Pan

The 7 Biggest Blunders You Don't Want to Make Choosing a Shower Pan | Innovate Building Solutions | #ShowerPan #ShowerPanels #DecorativePanels

Updated July 16, 2023

Since you’re reading this article you deserve a round of applause. Learning about shower pans is as sexy and ‘interesting’ as seeing your Mother in Law ‘attempting’ to look young with a skirt which is too short or pants which are too tight. Not a pretty picture. Certainly not sexy.

Shower pans literally get walked on and ignored daily. They get no respect.

However, I’d argue they’re propping up the entire ‘show.’ The show is your fancy shower heads, niches, contemporary sleek wall panels, tile surrounds and body jets people do notice.

If your base fails, you’re in a heap of trouble. You can throw in the dumpster all the cool features above the base (and your dollars – literally – down the literal drain with it). Sure, you can ‘cheap-out’ buying a low-cost shower pan or ‘zone out’ with no thought put into the design of a shower base. However, if you take this route as they’d say in high school Latin class – caveat emptor (that’s a fancy term for ‘let the buyer beware.’).

There’s a huge (or hugely as Trump would say) price to pay for a shower pan which fails, is designed incorrectly or doesn’t work as a family member ages and their mobility goes in the wrong direction.

Shower Pan Selection: Ask Yourself These 2 Game-Changing Questions

  • Question 1 – What are the biggest mistakes, blunders, pitfalls (insert your negative adjective here) when selecting shower pans? The more important question is this second one.
  • Question 2 – How can I avoid the problems posed in question 1 to save time, money and aggravation having to ‘re-remodel’ (not a word, but it happens in reality) or throw away a costly shower purchase?

The purpose of this article is simple. Provide the answers to question 1 and outline the 7 biggest blunders I’ve seen in bad shower pan purchases through my years (note – when I started in the bathroom remodeling business I had more hair, and none of it was grey either!) Next, I’ll cover question 2 and give you tips to make sure you don’t fall victim to the mistakes in question 1. In addition, I’ve added a ‘bonus question’ – #8, because if you’re like most people (and NOT made of money) – you’ll also care about cost.

Shower pan blunder #1 – Looking Beyond Tomorrow: Why Short-Term Shower Pan Choices Could Cost You Later

Your builder – without any input from you –will use the ‘path of least resistance method” and install the cheapest pan (a fiberglass tub/shower combination) or in luxury home get their tile guy to do the tried and true, a ceramic tile surround. In both bases they’ll use a standard 4” to 5” high step over curb for the pan without any direction from you.

This 4” or 5” high curb is not a problem ‘initially’, it’s the ‘eventually’ which can get you into trouble. Initially you and your family members are healthy and stepping over a shower curb is a breeze. Eventually your mobility may not be as good. If you can’t lift their legs up over the shower curb, you’ll be pulling out your old base for a new one.

Preventing Short Term Base Choices

Spend time researching zero threshold, barrier free, and low profile shower pans. If you’re not familiar with these options, they are designed to be level with the bathroom floor or have a small curb (from 1 1/6″ to 2″ high). They are not only safe but can also look cool and contemporary.  The first picture below shows how a finished zero threshold shower base system with tile looks after it’s completed. It will put you in the ‘double-bonus’ as they say in basketball – safe and stylish. The second photo is a straightforward-to-install acrylic roll in shower pan. Your builder or remodeler may like this one best because its super-simple to install. The last photo shows a fun black marble low profile shower pan which will give your bathroom the ‘wow’ factor most people don’t know is possible with a shower pan. Learn more by watching the video below on how to compare a low profile vs. ramped vs. a zero entry shower pan.

You need to note, just because you’ve found a better long-term shower pan selection doesn’t mean your builder will ‘embrace’ your choice. You’ll need to explain to your remodeler or builder why you need this product and provide them with installation instructions. If they still refuse to get you the pan you want, you may to become the “Monty Hall” of shower pan purchasers and look to hire the builder or remodeler behind door #2.”

Shower pan blunder #2 – Don’t Fall for Cracks, Yellowing, and Leaks in Cheap Shower Bases

A cracked shower pan which leaks onto your brand-new mahogany dining room table in the floor below with the fancy chandelier and tray ceiling is a bad day.

Here’s a fact (not exactly rocket science) – all shower pans aren’t created equal.

If you’re building a new home – builders will pack your home with cool features in the places, you’ll notice. Granite countertops. Large windows in a great room. A tray ceiling in the bedroom. What builder’ won’t do is put much economic value in features they feel you’ll pay little attention to (until it’s too late). One example, is the kids Jack and Jill bathroom off the hallway you’ll get a fiberglass one-piece shower surround. It’s the cheapest, slap-it-in solution. If you’re doing a tile shower they’ll have their ‘tile guys’ put in a mud-set pan base (basically a vinyl liner with concrete sloped in the pan).

These cheap solutions can become your future nightmare. These bases have a higher failure rate of cracking and leaking (or yellowing and looking ugly).

Avoiding Pitfalls of Buying Cheap Shower Bases

The simple advice is don’t cheap out on your shower pans. Upgrade to a solid surface or cultured granite shower pan  with guarantees which range from 10 years to lifetime guarantees. It’s not just guaranteed with your builders fabulous (sarcasm intended) one-year warranty. If you don’t want to spend as much, another smart option is a cast acrylic pan which has been reinforced with a multi-density fiberboard underneath (like you’ll see in the picture below). This isn’t your cheap -grab-off-the-shelf-pan you’ll pick up from the big box store. It won’t flex and creek like those low-budget acrylic pans.

If you’re doing a tile shower use a waterproof ready for tile shower pan or underlayment systems like those from Wedi Corp or Schluter. These products ensure moisture which gets through the grout joints, won’t get through the shower base underneath it (more about this later).

Shower pan blunder #3 – Ignoring Drain Location: The Hidden Pitfall of Shower Remodeling

When you’re remodeling, drain locations are a BIG thing. If your existing shower pan is in poured concrete moving it will be dusty, dirty, time consuming and expensive. If your shower is on the second floor changing where the drain is at will be more difficult than having complete access from the basement below (in the case of a first-floor shower with an unfinished lower level).

If you buy your shower pan first, dig deeper about your drain location, so you won’t be sorry and end up sucking up unnecessary expenses to move plumbing or eat restocking fees IF you’re able to return the standard pan.

The Crucial Role of Drain Measurements in Shower Pan Selection

Take approximate measurements (with the pan still in place) of your existing shower pan and it’s drain location. If you’re looking to use the same shape and same-size shower, see if the new pan drain location will line up with the drain hole in your existing shower. Look for standard pans – if possible – to save money. For example – if you’re doing a tub to shower conversion a low profile 60 x 32 shower pan like the one pictured below will be perfect (especially if you want to go from an alcove shower to a corner shower).

White marble solid surface low profile shower pan 60 x 32 size for a tub to shower conversion

If your drain location is not standard, your choice will be to move the plumbing or buy a custom shower pan. In many cases the more ‘expensive’ custom shower pan will actually result in a lower total project cost because you’re not paying a plumber to relocate your pipes.

Shower pan blunder #4 – Steering Your Bathroom Remodel: Why You Shouldn’t Let Builders Decide Your Shower Pan

Just because you’ve hired a builder or remodeler doesn’t mean they always have your best interests at mind. If you think about it, most builders and remodelers #1 motivation is….


Profit is not a dirty word. You need your builder to make money. You want them to make money, so they’ll be around if you need warranty repairs. However, you need to have a longer-term perspective for a shower pan purchase than your builder. Once your warranty is up – they’ve moved on to the next job and you’re on your own to deal with the maintenance or costs of a bad purchase.

Get Details on Your Builder’s Shower Pan Options Upfront

Before you sign on the bottom line know specifically what shower pans your builder or remodeler will be installing. Take time to research them and check out on line reviews. If it’s a site-built system, ask who(m) will be doing the installation (who are they subbing this work to). The reality is a site-built shower pan (like the mud set ones I mentioned before) are only as good as the specific human being doing the installation.

Shower pan blunder #5 – Avoiding Shower Pan Choices as Demanding as Teenagers

Here’s two glorious images.

(Image 1) You’re on your hands and knees ‘attempting’ to clean the dingy brownish dirt off the bottom of your fiberglass shower base.

(Image 2) You’ve pulled out the dreaded nylon bristled scrub brush and hydrogen peroxide and you’re ready to ‘go in’ and do battle with your moldy grout joints in your shower base.

When you bought this home, you realized fiberglass showers were cheap. At the time that seemed like a good thing. Today you know how hopeless the cleaning process can be.

Your tile shower looked BEAUTFUL when it was first installed. Now you’re seeing how much of a pain in the butt this grout maintenance thing can be.

Cutting Off Shower Pan Maintenance Headaches at the Pass

Remember the old saying, ‘an ounce of prevention is worth a pound of cure?’

Instead of choosing a cheap fiberglass pan for a hall or kid’s bathroom, go one notch up and select an acrylic shower pan. They are available in standard sizes, fun shapes, are simple to clean and cost effective.

Unique curved acrylic shower pan | Innovate Building Solutions | #acrylicshowerbase #AcrylicShower #ShowerBase

Instead of choosing a tile shower pan, use a solid surface base if you want to do a curved glass block shower. They come in 51 colors and have textured floors, so they aren’t slippery. If you’re asking, “Mike – will they be more expensive than the tile base?” The simple answer is – in the short-run yes. However, in the long run you won’t have to worry about the base cracking or leaking, or spending time hiring ‘Mr. Grout Joint Cleaning Dude’ (the new-fangled grout joint cleaning franchise) to waste your afternoon and money cleaning dirty, moldy joints.

Shower pan blunder #6 – Making the Call: DIY Components or Ready-to-Install for Your Shower Floor Plan

What would you rather work with:

1) A shower where you’re installing a sloped shower pan and then installing a curb component next to it or…

2) One where everything is all in one unit?

If you’re like most when it comes to DIY remodeling, the less components the better. Anyone who would rather be spending more time putting their shower pan together than golfing or hanging out with friends needs counseling.

Simplify Your Bathroom Remodeling Project, Order a Waterproof Ready Shower Pan

It’s simple to order a waterproof ready for tile shower pan to eliminate the hassle of joining the curb component to the shower pan. Ready for tile bases come in all shapes and sizes and work with various types of glass enclosures. They are lightweight and straightforward to install.

Shower pan blunder #7 – Shower Design Strategy: Choosing Glass Type Before Pan Shape

You wouldn’t pour concrete or have a mason build your basement foundation if you hadn’t planned the 1st and 2nd floor levels. You obviously want the upper floor levels to fit exactly on your foundation. This same logic is true with a shower pan.

I’ve seen people who’ve bought a standard fiberglass shower pan with a 2” wide curb and then call to do a glass block shower wall (which is 3 1/8” wide). The block wall will not fit onto the curb depth.

I’ve also seen homeowners who have wanted curved glass walls, but the curvature of the base they’ve built did not fit the curvature of the glass. This is a HUGE problem.

Choosing the Shower Glass First

It’s not hard to solve the shower pan shape problem when (using a borrowed version of the Stephen Covey quote) you ‘begin with the glass in mind.” Determine the shape and type of glass you want to use. For example, if you love the colors and low-maintenance aspects of glass blocks (which cannot be cut) you’ll want to work with a glass block shower designer to help with a layout before building or buying your base. What’s nice is then the shaped glass wall can be designed to fit like a glove with either a solid surface shower pan or a ready for tile one.

Bonus – Shower pan blunder #8 – Navigating Shower Pan Costs

If you’re not made of money (as Dad used to say), I get it – and can respect it. Most of us don’t go to work for the ‘fun of it.’ We need to earn a living to afford a nicer home and provide for our families. So, one of the challenges you can have in choosing a shower pan is to get ‘all excited’ about a certain type of pan and then have your hopes dashed when you find out how truly expensive they are. That’s why I will be providing (and adding to the section below) articles about the cost of shower pans. You need to be grounded (no shower pan pun intended), so you invest in the best pan for you.

How to prevent shower pan blunder #8 – The best way to deal with potential shower pan sticker shock is to get cost information BEFORE you do too much research. And there’s nothing like finding out you wasted a lot of your time. That’s why in the area below I’ll provide links to articles about the cost of various types of shower pans. The one I finished thus far is the cost of cultured marble shower pans and cultured granite shower pans. When the other articles are done, you’ll get links to those as well.

How much do cultured marble shower pans cost | Innovate Building Solutions

Beating Shower Pan Sticker Shock: Get Cost Information Early

As I admitted up front shower pan selection, design and construction isn’t exactly the sexiest topic going in bathroom remodeling. However, the failure to give the ‘foundation’ of your shower enclosure it’s due, can have nasty consequences. A lack of focus on your shower pan can result in having to ‘remodel your remodel’ or unnecessary scrubbing or maintenance.

I hope identifying these 7 shower pan blunders (and the tips to make sure they don’t happen to you – along with the bonus blunder #8) are useful for you in your next shower remodel.

  • Jen – thanks for your comment. I like to have fun when I write. I’m sure my style isn’t for everyone though – but I appreciate you reading it and hope you found value in its contents. Mike

  • MimiLee – sorry you’ve made a few errors with the purchase of your past shower pans. There are a lot of options with bases, shower wall and shower doors – and it can be helpful to have someone who works with these guide you through the process. If you (or someone you know) needs help in a further project please have them contact us (shower projects are our specialty). Thanks for reading my article and feel free to call us if we can help further – Mike (877-668-5888)

  • Shower pan blunder #9 is that you order a white shower pan before considering how the “matching” white tile will look with the other shade of white on the walls. I am really struggling with this at the moment and wish I would have considered my color swatches first. Also, after having a low profile Dreamline shower pan in another home, I actually went with a higher curbed Swiss Madison acrylic one this time so water wouldn’t get on the floor when using a shower curtain. I didn’t want to put glass shower doors in this application. Now I see I may have a mistake there too, lol.

  • Nancy – we certainly can create a wall panel kit and pan kit to do your project – whether you need a ‘standard size’ or a custom size. I’ll include a link to the standard complete shower alcove program – but call us (877-668-5888) and we can go over your specific project and come up with a solution for you – thanks for your interest. Here’s the standard complete shower kit link –

  • I want to update my mini master bath combining a freestanding tub/shower. Don you have a pan and wall kit for something like this?

  • The contractors at my house shower base in my house incorrectly , they didn’t put mortar on the floor before installing the acrylic base. It was a Dreamline alcove shower system that cost over $2500 canadian. I have a tiled walk in shower.

  • Mike – that’s a tough one since everything else is OK. Maybe you could try (if you don’t have one today) to add an exhaust fan to remove more moisture from the air in the bathroom. Mike

  • Hi. I had a house built in 2016. Was working 7 days a week and was on the road at the time. Builder sure charged top dollar for everything but did some stuff cheaply. My master bathroom is wall tile to fiberglass pan. The one corner towards the entrance door is constantly getting black mold on it. Everywhere else has been perfectly fine. Twice I have removed all the caulk and let it dry. Put in silicone and let it dry for a few days. It keeps coming back!!! Any suggestions or recommendations?

  • Lilia – I looked up the Krion shower pan – although I’ve never seen one in person. It appears that it’s an acrylic pan with a linear drain. I like the looks of it, but I didn’t find much specific information on the site about it. I also have a pan in a contemporary reinforced acrylic which looks like this also – I’ll include a link here with an MDF underlayment with acrylic on the top. Let me know if we can help further – Mike …now here’s the link –

  • Hi Mike,
    Thank you for providing all the useful info re shower pans. What is your opinion about the Porcelanosa Krion shower pans? Thank you, Lilia

  • Christy – while this isn’t easy to ‘pull off this operation,’ it is possible. I know many years ago our remodeling division did this type of job. They cut up the wall about 12″, waterproofed around the sides then installed a new pan (with new tile – we used a contrasting tile color to not try to ‘match’ the old tiles which were very cool old vintage units). For the base underneath I’d either recommend (if you want to stay with tile) a waterproof system like Wedi or Schluter – of if you want to ditch the tile – and the maintenance which comes with it use a solid surface or cultured granite shower pan (see this link – I hope this gets you on the right path and if you need more input call me – or one of my teammates – at 877-668-5888 – Mike

  • Mike, You are right that shower pan and design are very critical. The contractor who hired by previous owner didn’t do a right job – tile shower pan is leaking 3 years after remodel. Is it possible just to remove the tile shower floor and the bottom section of the shower wall (also tiles) and install a new sturdy shower pan and tiles of the bottom section of shower wall? Or the whole shower needs to be redone? Thanks!

  • Lisa – I think Kohler makes a nice looking enamel coated steel base. I haven’t used them, but have seen them at international trade shows and they look very nice. I would evaluate what warranty they offer against chipped or discoloration before going ahead though…..Mike

  • Gail – there are several types of low curb shower pans on the market. I’m not a big fan of the fiberglass pans – which while they are cheap – tend to yellow over time. The two I like the best are a contemporary reinforced acrylic pan (which is pretty cost-effective) and a cultured granite shower pan (which while more expensive than the acrylic has a ton of options with sizing and is as durable as a rock). I’ll include links to both products below for you to check out. If me – or my team can help – please call 877-668-5888 – Mike (contemporary reinforced acrylic pan) (cultured granite and cultured marble shower pans)

  • We are replacing our shower put a lower pan to step in . I have bad knees. Thought about tiling the walls. Drain in center of tub shower head on right wall. Any suggestion on what we should do. We live in mobile home. Thanks

  • Barb – I would recommend a low profile shower pan (most likely made of a stone solid surface since it seems you may have a custom size or a one level wet room bathroom. Feel free to call us at 877-668-5888 if you have any additional questions – Mike

  • I am replacing my tub for a shower. I live in a moble home and the tub measurements are 27x56x73 to the shower head. My drain is in the right end of the tub “looking at it”. I have to replace the floor under the tub before I can put the shower in. What kind of shower would you suggest. I am no longer able to get into tub.

  • Cathy – thanks for your comments. While I personally haven’t used the Wedi linear drain product (although I do think our installation team has) I don’t think the contractor is doing you a disservice using the 32 x 72 pan. When you’re dealing with a modular system like wedi the base component is not necessarily the size of the entire pan (and since you have a 48 x 84 pan – which is a nice size) you’ll want to use the largest component you can find in the wedi line. Regarding cutting the drain hole, I might suggest to give Wedi a call and talk to a customer support person. They will know the ‘ins and outs’ of their line (a line we don’t wholesale) better than I. I hope this helps you some – Mike

  • We are building a new 48″ x 84″ curbless shower with an approx 47 or 48″ linear drain on one end. Our contractor purchased a Wedi pre-formed shower pan system to install. He purchased a 32″ x 72″ system and I understand that the slope can still work because the sides get mudded and sloped in kind with the pre-formed pan. What I don’t understand is how this affects the pre-cut linear drain hole which is only about 27″ wide. Is it a good Idea to cut the sides of the pre-cut drain hole to make the linear drain fit or is our contractor doing us a disservice by using this smaller pre-formed pan with a too small pre-cut drain slot?

  • Carl – I talked to Rob – our VP of Operations – about your questions. He thinks what you’re planning to do with the base here is a perfectly fine idea. The only additional thing he said we might do (especially if the base wasn’t too thick at the bottom) would be to put concrete underneath the pan to provide more stability. Mike

  • I’m curious if you can tell me. I have a better quality acrylic base (with adjustable leveling feet) can I install this on top of a tiled floor? It seems like this would be “more waterproof” and as the pan is curved it would alleviate my need to to cut the tile to match a curved edge.

  • Kathryn – thanks for your email. Unfortunately I don’t know a contractor in your area – but if you find one we can certainly assist you with the custom shower pan. Sorry I wasn’t of more help with the contractor – Mike

  • I am remodeling a house that was flooded in 2016. I want a walk in shower with later ability to wheel in a chair. There has never been a shower before so I can do whatever. However the shower pan size has to be custom fit. The shower walls will be tin. I live in Louisiana so any suggestions as to where I can find someone to help with this project? Also my house is 9 feet from ground to inside floor and welded to steel I beams on feted intro the ground. Concrete block stack supports are also placed underneath as well. So basically house on stilts.

  • Patty – thanks for your nice comments. I’m glad my article inspired you. I’ll plan to email you and see how we can help with the project for your father. Showers have come a long way – and I think for the better! Mike

  • WOW! I am in the planning stages of my master bath renovation and I love your article! I work for a hotel company and have seen my share of showers and I probably have put more thought into my shower pan than any non (shower pan industry person) ever! My 89 year old father lives with us I initially wanted a roll in shower. However after this article I want the low profile cultured granite shower pan! It is perfect for my project! Do you carry products along the lines of Mincey Marple shower walls? I love the no grout aspect of that product.

  • Thank you for the great article , Where can one purchase these outstanding unit, at my local Home Depot?? help…george
