You know I never shy away from a tiling challenge, so I jumped in hammer first when it came to building the walk-in shower for our new master bathroom. MysteryMan only balked for a minute or two, because hey– his man-cave bathroom turned out fairly awesome– and you can’t argue with results.
I’ve been picking the collective brain of our plumbers, the internet, and anyone who seems mildly interested in how to build a shower bench, and I’d call the rough framing portion of this project a success. Here’s how it went down.
This is possibly the most uninteresting image I’ve posted to this website in the last four years, but it shows what our plan was.
This is what we started out with:
We taped the wall off first to help us visualize. Then it was time to get out a couple of saws and the framing nailer. To start, because the half wall would only be attached at the floor and on one side, I cut a hole through the subfloor to attach a “post” to the floor joists below. This gave the wall some added stability.
These are two 2×4′s sunk about 8″ into the floor and nailed to the joist. I built the frame of the wall to fit around these.
The spacing of the one stud is 12″ off the back of the wall. Traditionally you’d make this 16″, however we decided to put a bench 12″ off of the back of the shower so it made sense to put the stud in this position for nailing. See?
Framing in the shower bench consisted of building one itty-bitty wall and then nailing a 2×4 into the back of the shower wall to support the plywood top.
The bench is 12″ deep. Standard seat height is around 17-1/2″, so I subtracted 1/2″ for the tile board and 3/4″ for the plywood, and built the frame to 16-1/4″ in the back, and 16″ in the front so that it slopes forward for drainage.
In order to get everything attached correctly, there was a lot of blocking added to the existing walls. For the bench, blocking was added here…
And here…
For the half-wall, blocking was added here…
It’s not pretty, but it works. (I’m pretty sure that’s a metaphor for how I look most days.)
To finish everything off, we added 6″ pieces of blocking around the bottom of the shower, and around the bench. Rubber will be attached to this to waterproof everything.
The bench also got 3/4″ plywood attached to the top…
And to the front.
I have plans to finish this with tile on the front, and a slab of granite or marble on the top.
To finish everything off, we put a 4.5″ sill in, and nailed it into the post for the half wall as well, adding additional support.
So, not bad for a little weekend work…
Up next is the rough plumbing, then waterproofing and getting the backerboard on for tile.

If you end up using the adhesive for the rubber shower membrane (I had to attach a second piece to cover the front step), be very careful. It’s the nastiest stuff I’ve ever smelled — and what convinced me to finally get a heavy-duty cartridge filter mask.

Hey… looks just like my shower! BTW, you said this:
“Standard seat height is around 17-1/2″, so I subtracted 1/2″ for the tile board and 3/4″ for the plywood, and built the frame to 16-1/4″ in the back, and 16″ in the front so that it slopes forward for drainage.”
Are you going to pour a mud bed for the base? Cuz if you are, wouldn’t you need to consider that thickness in your bench height? Maybe you’ve got this all figured out, but I’d hate to go away not saying anything and find out you’re kicking yourself later.
Keep up the good work!

good luck with this project! we did a custom walk-in shower and LOVED it. the hardest thing with ours was getting the floor to slope {and drain} properly and then building a niche into the wall for shampoo bottles.
we used the Schluter®-KERDI membrane and had to reinforce the floor (from underneath) to support the extra weight of everything.

Hi
Really enjoy your website.
My sister and her husband are building a cottage and they found the John Bridge website and forum (www.johnbridge.com) really useful. They have a disabled son and the shower has to be curb-less so they are going with the Schluter-Kerdi membrane system mentioned above.

we have done dozens of walk in, curb less, barrier free showers he in Tampa, Florida and surrounding area’s.
I agree with Catherine, the JB Tile Forum is a good place for someone to go for info. I help out on the site and there are plenty of tile pros offering advice.

Hi, I really enoyed diy-walk-in-shower step 1. I would love to see the rest of the steps, plumbing and tiling, but I couln’t find them anywhere on your site. could you please send the link to the remaining steps.

What are the overall dimensions for this shower?

Hi,
I liked the post idea and how you secured. Did you cut a half lap joint in the post to secure to the side of the joist?

OSB in a shower would make me nervous. In theory it should never get wet…but if it did for some reason the OSB would swell and tiles would buckle. Too late now…this sucker is sealed up and done. Should be fine, would just make my rear pucker.
