Bathroom Remodel 911

Have you remodeled yourself into a corner and have no idea how to work your way out? Before you get trapped any further: Stop! Some common bathroom remodeling mistakes have quick, easy fixes. Others, not so much. 

Either way, here’s a guide to the most common bathroom blunders we’ve encountered and how to fix them, with and without (but usually with) professional help.

Get the Right Backerboard, Jack, or Do It Again

The biggest mistake an amateur bathroom remodeler can make is using the wrong product for the walls behind and around a shower enclosure. Although some companies manufacture membranes that supposedly let you use regular old sheetrock or green board, the right way is to use what’s called cement board.

You see, drywall is made of two basic materials: a layer of a naturally occurring mineral called gypsum sandwiched between a few thick sheets of paper. 

Yes, paper. 

If you’ve ever dropped a book you were reading into the bath, or spilled a soda on a magazine, you know what water does to paper. It warps and expands it into a sort of Frankenstein’s monster version of itself, never to regain its original form again. 

Drywall is far less expensive than cement board, and many DIY bathroom remodelers either don’t know the difference, or they do know and take the risk anyway, thinking the shower or tub enclosure will keep the water away.

When drywall gets wet it can rot and mold, warp and fall apart.

Generally speaking, it will indeed prevent splashes. What it won’t do, however, is protect the backerboard from airborne humidity. As most folks know, it doesn’t take more than a few minutes in a hot shower to turn most bathrooms into a sauna.

Neither an enclosure nor membrane will protect against 100-percent humidity, and it won’t be long before you’re drywall starts warping.

It will, however, take just long enough for you to finish the job, and that’s what makes using the wrong backerboard so devastating. By the time you realize the repercussions of your mistake, the project is finished and you’ll have to tear it all down to fix it.

Cement board is a combination of—you guessed it—cement, a synthetic fibrous material such as fiberglass, and a few other additives that give the board strength. The advantage of cement board is that it is impervious to water, either directly through splashing or indirectly through humidity. It is the only correct backerboard to use in the area surrounding a tub or shower.

Cement board is waterproof and the only approved backboard for bathroom construction.

The only way to fix the damage caused by using the incorrect backing material is to tear everything down as carefully as possible, salvage what you can (such as prefabricated enclosures and tubs) and start over from scratch. 

Color Me Whoops

You’ve decided to go with a light color palette, which you want to compliment with soft textures. That’s great! But don’t make the mistake of using a matte finish in your bathroom, or you may end up redoing more than just the paint job.

Interior paint can be anything from shiny to dull, and everything in between. It achieves this effect by the degree to which it forms a shell on its surface. 

The correct level of sheen for bathroom paint is satin or semi-gloss.

Matte, the least shiny type, has almost no sheen at all. The surface is noticeably textured—not quite “rough” but far from smooth. This leaves the wall beneath it open to the elements, which, in a bathroom, means heat, water and humidity. Not only do they not protect the wall, matte finishes are difficult to clean, as scuff marks and spills don’t wipe up easily. 

From there, finishes increase in shine from eggshell to satin to semi-gloss to full gloss. Most contractors recommend satin or semi-gloss for bathroom walls because both offer a good degree of smoothness, which protects walls and makes cleanup easy. 

Eggshell is still too porous, and full-gloss, aside from reflecting light in a less attractive way, also reveals the smallest defects of the wall beneath it, which can be especially telling after a remodel. 

Thankfully, so long as errant splashes or humidity haven’t penetrated the paint and started disforming the walls, all it takes to remedy a bad paint job is a few of coats of paint with the correct finish. 

Pro tip: if you choose the same color as what’s already up it will take fewer coats to fix your mistake, which will save you both time and money.

Need to Vent? So Does Your Bathroom

A lot of people don’t realize this, but bathroom fans aren’t just for venting malodors. In fact, even though it’s quite a courtesy to run the fan after doing your business, that’s not even their primary purpose. 

When you take a shower, aerosolized water fills the air, which quickly ramps the humidity up to 100 percent. At that point, the water begins to condense on cooler surfaces—that’s why your mirror fogs up. The fan helps regulate this, quickly bringing the humidity back to a comfortable level.

When it comes to proper ventilation, there are two mistakes that can have devastating consequences on your bathroom. One happens during your remodel, the other is one you keep making long after your project is finished. 

It gets more than just the stink out—bathroom fans are also there to remove humidity.

First, not installing a powerful enough fan will result in moisture buildup that can damage your paint, walls, flooring, cabinets—basically anything that stays in the bathroom. To make sure your fan will do the job, select a product that moves as many cubic feet per second as there are square feet in the bathroom. For example, if your bathroom is 5-by-10 feet, that’s 50 square feet, so look for a fan rated 50 CFS or better.

The other mistake is forgetting to use the fan every time anyone showers. If not discharged properly, over time the constant high humidity will result in excess mildew and weakened cabinetry (wood, especially the engineered variety, absorbs and will retain water, which shortens its lifespan). Paint may begin to peel and join seals may begin to erode.
