After studying thousands of bathroom photos and designing dozens over the past ten years, I’ve learned that not all bathroom design is created equal.

As a former engineer, my clients quickly learn that I’m a pragmatist. Form has to follow function, especially in a bathroom or kitchen. I don’t care how pretty it is or how cool it looks if it doesn’t work!

I’ll be honest, in my early days as a designer, I probably made all of the mistakes listed below. But, every job teaches me something new, and I never repeat those missteps again. If you’re getting ready to remodel or design a bathroom, make sure that you or your designer avoids these critical bathroom remodeling mistakes.

# 1 YOU HAVE TO GET WET TO TURN ON THE SHOWER

This list isn’t necessarily ranked in order; however, positioning the shower so you have no choice but to get drenched in freezing cold water every morning has to be the worst bathroom design mistake you can make.

The Shower Controls in This Bathroom Are Directly Opposite the Door NOT under the Shower Head

For some reason, people became convinced that the shower controls – the on/off and temperature valves – need to be located directly under the shower head. But, often the shower head is at the far end of the shower from the door, meaning you can’t reach the controls unless you step into the shower.

I have seen showers where the client keeps the shower head pointed towards the wall while they turn on the water. This doesn’t really seem like an optimal user experience for someone’s dream bathroom.

The worst shower layout is one in which you have to get into the shower and also close the door to turn on the shower so there’s no escape. Terrible! I’ve definitely encountered this setup in hotels, and it totally sucks.

So, how do you avoid this happening to you? Look at the plans for your bathroom and picture yourself opening the door and reaching for the controls. Can you easily access them without stepping into the shower and under the shower head?

Remember, most shower doors swing both ways so as long as you can open it one way and reach your controls, it works.

If you can’t, then another revision is definitely in order. You can usually fix the issue by moving either the controls or the door.

# 2 POOR OR BAD VANITY LIGHTING

Vanity lighting design definitely deserves its own post, and I am planning to publish one soon. My biggest pet peeve with many Insta-famous or HGTV-trendy bathrooms is the lighting design at the vanities.

If you have a smaller vanity (42″ or less), then often (but not always) your only solution is to place the vanity light over the mirror. However, for larger vanities, I think it’s a mistake to sacrifice optimal lighting for a cool look or fancy decorative mirror.

Vanity with a Sconce on Either Side of the Mirror and Recessed Can Above

Spacing vanity lighting so that it feels balanced and proportional with the mirrors and the cabinetry is a fine art. I agonize over it on every single bathroom project I design. My priority is always to provide a sconce on each side of the mirror with the bulb height between 60″ and 66″. When combined with a recessed can over the sink, the three light sources diffuse hard shadows.

If you’ve ever looked at yourself in a bathroom mirror and thought you aged 10 years, look up. I bet the light source is a downward facing sconce centered over the mirror.

#3 NOT PLANNING STORAGE APPROPRIATELY

A Double Master Bath Vanity with Tons of Storage and Drop Down Dressing Table

So often I see photos of beautiful bathrooms with absolutely terrible storage, especially in master bathrooms. The furniture style vanities can look really pretty but are they totally practical?

It’s so important to seriously consider everything you need to store in your bathroom both for the things you use every day in your beauty and hygiene routine as well as linens and other supplies like toilet paper. Once you understand everything you use on a daily basis, then think about the best way to store it. Do you have serums, moisturizers, makeup, etc. that needs to remain vertical? How tall are the products you use? How long and wide are your hair brushes?

I like to incorporate a variety of drawer depths whenever possible as well as cabinets with doors. The sink cabinet can be a great place for hiding the wastebasket. I also keep tall products like hairspray on a lazy susan from Container Store under my sink.

This Polished Nickel Medicine Cabinet From Restoration Hardware Adds Tons of Storage

I know medicine cabinets aren’t as sexy as a gorgeous decorative mirror, but they are ridiculously practical in smaller bathrooms. In the vintage style bathroom above, we only had room for a single 48″ freestanding vanity, so we maxed out storage for small toiletries by adding this polished nickel medicine cabinet from Restoration Hardware. I’ve lost count of how many times I’ve used this exact medicine cabinet because it’s very handsome, generously sized, and comes with an integrated light and electrical outlet. No more razor or electric toothbrush sitting on the counter!

#4 NOT INCLUDING A HAND SHOWER

Maybe you do your own cleaning and maybe you don’t. Either way, someone is going to be cleaning your gargantuan walk-shower at least every couple weeks. If you don’t include a hand-shower, then the only way they’ll be able to rinse down the shower walls is with a bucket. And, that’s really just mean.

I love my hand shower for both cleaning and for rinsing my hair. If you set it up correctly, you can run your main showerhead and your hand shower at the same time. It’s a more affordable version of body jets, especially if you mount the hand shower on an adjustable wall bar, which I highly recommend.

#5 TRYING TO CHEAP OUT ON PLUMBING FIXTURES

During my very first interior design related job – at the Great Indoors in Chandler, Arizona, 14 years ago – a very nice plumbing salesman educated me on the evils of cheap plumbing. He told me that cheap plumbing fixtures from big box stores or discount outlets are often made with cheap plastic parts that break instead of metal.

Fast forward ten years. I was freshening up the hall bathroom in our last house and bought an inexpensive version of a name brand faucet at a big box hardware store even though I warn my clients against this very thing. When we couldn’t figure out how to install it ourselves, we had to call a plumber. After two hours, he informed me he needed to go out and buy all new parts for the inside of the faucet because it was “cheap plastic junk.” So that $90 faucet ended up costing over $300.

I specify all plumbing for my projects through my sales representative at the local plumbing supply companies. They know their product inside out. They know all the parts and pieces that need to be included like valves, and wall elbows, and escutcheon for hand showers. And, they stand behind the product and help you when something goes wrong or needs replacing. They are completely invaluable members of my team.

I could have gone on and on with more bathroom remodeling mistakes that I see people make all the time, so maybe I need to write a follow up post. What do you think are the biggest bathroom remodeling or bathroom design mistakes people make? Are there any bathroom trends you’ve been spotting that drive you nuts with their impracticality?
