Questions re: DIY shower using wood slats

Hubby and I want a new bathroom. We plan to gut the current room and start fresh. We are toying with the idea of a shower that will mimic the outdoor wood shower we once had in Hawaii. Being this one will be in Minnesota, it will be indoors ;)

These are our thoughts so far: something on the walls for waterproofing (cement board?) and then the wood slats (rot resistant Ipe/cedar/teak maybe) affixed to the walls.

If we use cement board, is that waterproof? From what I've read, I think we would need to avoid products with gypsum and go for cement board with portland cement? And do we need to tile/or somehow coat the cement board before affixing the wood slats?

Also, any thoughts on this plan? Obviously it's a little unorthodox, but what would make it work? Would we be able to treat the wood with some product to enhance the richness of the wood, maybe give it a little more protection, or is that unhealthy in an enclosed space like that?

I'll try to post a pic of our inspiration showers.

Thanks much!

RE: Questions re: DIY shower using wood slats

I like your thinkin' and love stuff like that. I have built several outdoor showers at lakeside residences in my career and they are a lot of fun. I have used redwood, cedar, and cypress if memory serves. An outdoor shower doesn't have to be guaranteed against leaks but your indoor shower will. This brings me to my first question.

How would you preserve the integrity of the waterproofing of the walls while at the same time attaching the wood to the walls?

RE: Questions re: DIY shower using wood slats

Good question! Wish I knew the answer! However, now that I look at the pic again, maybe if I do it just as in the pic that would not be an issue? I could use more tile, and only have wood where it is attached to stainless steel poles?

Can wood be affixed to cement board with some type of adhesive?

RE: Questions re: DIY shower using wood slats

Can wood be affixed to cement board with some type of adhesive?

I'm not sure if that's feasible with the constant moisture issues. The wood will need to move with climatic changes and I'm not convenced the adhesive would hold up.

RE: Questions re: DIY shower using wood slats

Actually, we did this in one of our bathrooms about 25 years ago, and the bathroom is still in use--although we are ready to renovate. We used 6 inch tongue and grooved redwood boards laid horizontal. We put clear silicone caulking in the grooves at installation and caulked where it met the tub. We used multiple coats of marine urethans. We've re-coated every couple of years. We also did the celing over the tub the same way. The redwood was laid over blueboard; I don't think we even knew enough to use cementboard (we were young DIYers at the time) We've had no water/moisture issues. Unusual and it worked. the redwwod with the urethane has retained its rich color.

I'll try to post a photo tomorrow if need be.

RE: Questions re: DIY shower using wood slats

aekekk: Thank you so much! Its so good to know that this can work. I was starting to think that the bathroom in the picture I posted before was all for show and was not functional. I picture would be very much appreciated. Also, how did you affix the tongue and groove to the blue board?

Thanks again, I had all but given up! I'm very excited! And thanks for the info on how to seal the wood, good to know the urethane help maintain the woods beauty. Was the lovely scent able to come out through the urethane?

RE: Questions re: DIY shower using wood slats

have you decided if you will do the wood shower, we want to do ours in cedar, so any tips you find that work, please post them, especially about the type of sealer and how to attach.

RE: Questions re: DIY shower using wood slats

I'm not any farther along in the planning. Still don't know how to attach the wood to the wall, but have wondered about "propping" it in place with architectural elements that look nice and also keep it firmly in place. For sealer, I am thinking about Waterlox Sealer Finish, and/or Waterlox Marine finish.

I was thinking I might get this book, seems to be a fair amount of "wood" bathroom ideas in it. And I can't quite tell, but it seems like it's kind of a step by step book,so maybe it will tell us exactly how to do it? Maybe not, maybe it's just ideas. AT this point I'm full of ideas, it's practical "how to" I need.

I wish the wise people of this forum would chime in just a bit more on this one, hint hint ;)

aekekk, can you tell us how you attached to the wall? And can you post a pic?

HOpe you have good luck with this, we won't be do anything til summer at least.

RE: Questions re: DIY shower using wood slats

Cement board is NOT waterproof. Moisture can pass through cement board. You either need a vapor barrier behind the cement board, or some sort of waterproofing on the surface of the cement board. And for the record, I think that wood on the walls of an interior shower is a bad idea and maintenance nightmare.

RE: Questions re: DIY shower using wood slats

I once had an architect spec out a bathroom that was teak strips over Kerdi, the adhesive was to be Bostiks Best.

Bostik's is a GREAT adhesive, it's what I use for glue-down flooring.

Schluter said it would work.

Bostiks said it would work.

I didn't like the homeowner, though, so I turned down the job and didn't build his house.

RE: Questions re: DIY shower using wood slats

terriks: thanks for the reminder on the vapor barrier. We might just take our chances with the wood shower. I figure if boats/canoes etc can be made of wood, a shower can have some wood in it. We had an outdoor wood shower in Hawaii and it was great. Course, I'm not planning to mimic that rental, that shower was made of treated lumber. The view made up for the type of lumber.

Mongo: thanks for the tips on adhesives, etc. So, install kerdi all over, then glue the wood to the cured kerdi (maybe tongue and groove with silicone caulk between the boards as aekekk suggested)? Maybe with kerdi silicone would be unnecessary. Then again, why have water accumulate in the grooves if you can avoid it.

PS, Mongo, remind me to never irritate you, or you might stop advising me ;)

RE: Questions re: DIY shower using wood slats

This is one of those times that I'll tell you not to take my previous post as gospel.

I'd recommend you call Schluter's tech line and tell them you want wood over Kerdi. See what their advice is.

Had I proceeded with the teak over Bostiks over Kerdi, the combination is unorthodox, so I'd have gotten the "thumbs up" from them in writing.

So call Schluter and get whatever advice you can directly from the horse's mouth. Some of their reps go by script only, some go beyond the written words and will help you think a process through.

You might want to check out this webpage, and the other pages on this site, for ideas and/or products, including teak shower floor panels. There's also a discussion of these products somewhere below on this forum.

Here is a link that might be useful: teak shower floor panels

RE: Questions re: DIY shower using wood slats

How about this: Assemble panels with your slats vertical and screwed from the back to horizontal battens, which are screwed with stainless machine screws into threaded inserts anchored in smooth stucco. The machine screws would be accessible through the gaps in the slats so the panels could be removed for cleaning, and caulking could seal the screw/anchor connection. The idea of stucco would be that you have a continuous, pretty waterproof surface (think swimming pool) that would back up your wood. Gary

RE: Questions re: DIY shower using wood slats

Wow thanks for all the great advise.. I am pretty sure we will do wood as just feel it can be done, and love the look of the outdoor showers. Printing off all the great info and will decipher.. we may not start our project for a couple of more weeks, but definately want to have it done by June.. so will update what we do and will check the site for more great information.

RE: Questions re: DIY shower using wood slats

Thanks again everyone for the advice. We hope to make this happen, sometime this summer maybe.

RE: Questions re: DIY shower using wood slats

I will be starting my wood shower walls in the next month. The shower is 7' x 4'. The floor will be tile and the ceiling will be copper. The walls will be 6" T&G cedar installed horizontal. I am installing cement board and sealing the seams with thinset just as you would for tile. I will then waterproof the cement board with a paint on waterproofer.(Red Guard is one brand) The first piece of cedar will be face nailed with galvanized finish nails. The subsequent pieces will then be nailed through the tongue at a downward angle and into the studs. Each subsequent piece then covers up these nails. You will have to mark the studs on the ceiling and floor before installing the cement board so you can locate them later. I use a 15ga. finish nailer. This is the way I install T&G wood ceilings in homes. T&G flooring is installed in a similar way except they usually use cleats or staples instead of finish nails. I may also glue the pieces on with a construction adhesive, but I don't believe it will be necessary, as the nails typically hold very well. I will finish off by sanding the walls flat and then putting on several coats of a marine urethane. Hope this helps. If I finish first, I will post some pics. If you finish first, please do the same. I would enjoy seeing the finished product. THanks.

RE: Questions re: DIY shower using wood slats

Won't punching a hundred nail holes in the Redguard pretty much eliminate its effectiveness as a waterproofing membrane? Or will the urethane make up for that? I am curious because I am thinking of doing something similar in my guest shower.

RE: Questions re: DIY shower using wood slats

Bryan,

I am doing wood panels inside my shower too (this is a tub surround). Two walls will be wood and one will be marble. The marbled wall will use kerdi as the waterproofing membrane.

The wood is 1" thick bubinga. I found (in LA) a bundle of lumber that came from a single tree which means it is all book matched (!!). So each panel is simply two pieces of lumber glued together. These will be screwed to the studs. Then I am using a prefab shower panel for the shower controls. So only a hot and cold outlet through the solid wood panels.

Will post photos in about two months when the bathroom gets done :)

RE: Questions re: DIY shower using wood slats

If I do a diligent and correct job with the urethane, the nail holes should not be a problem. The red guard probably isn't even necessary. The concrete board isn't necessary either as long as the urethane seals everything up. Concrete board is used with tile because it will still hold tile and not mildew and rot even if moisture does find it's way behind the tile. So the concrete board is just my first line of backup in case this happens. The red guard is my second line of backup. I'm hoping that neither is actually needed.
