I’m considering creating a sunken tub/shower in a raised floor home. I want to use the space under the joists to contain the tub. I was wondering if anyone else has attempted such a project, whether it would be against code and any other tidbits of advice you can provide.
Thanks!

The closer to eye level you make the floor the nastier it looks.
Hair balls take on a whole new meaning.
i have seen it done in a wood framed floor system, the house was probaly 20 to 30 years old and the tub looked like it was sunken when the house was built.
the joists under the tub where headed off at both ends of the tub, and a suitable platform was built up from the concrete slab underneath.
the tub, a normal fglass unit was mounted so that the rim was about 6 inches above the finished floorcaulking is not a piece of trim
I like your comment about having the rim be 6 inches above the floor, especially considering the previous comment about the floor looking bad at eye level (never thought of that). This would also give a nice separation between the tub and the floor yet still allow it to be sunken. Thanks.
you're welcome, im considering the same idea in a new ensuite over a crawlspace in my new fiances house for us
main problem with a retro fit will be appropiate heading off the joists and supplying adequete support for the tub off the slab belowcaulking is not a piece of trim
in a raised floor home Is the finished floor raised up off a concrete slab? or what? Is there a crawl space under the floor? One of your problems will be supporting the weight of the tub, water, and body.
Do it right, or do it twice.
First, Just curious "Terdog"?
Anyway, I have never done this, but I do have a book with this spec, in it. 1. For a tub over a crawl space, they show a conc. slab built up to the bottom of the tub. Then they set the tub on top of 1/2" mortar or plaster. Lastly, they surrounded the tub with fiberglass to retain the heat.
It's a high school nick name. Terdog, Mowgli and Tomcat. Three crazy rebels causing hell. Anyway...
This makes a lot of sense and is very clear. Thank you!
It is a raised floor wood joists with your normal 2 foot approximate crawl space. It is supported by block foundation built in the 1950's. I had considered making the tub surround out of concrete and actually placing the slab at ground level with sides that extend up to floor level instead of what has been suggested as supporting a traditional tub with the joists. This would alieviate the problem of the weight since the weight will be supported by the ground.
What are your thoughts?
They call it a Roman Tub. Most house drains are just under the joist which is not low enough for a Roman tub. Old code detail show minimum 6" thick walls with waterproof membrane into a showerpan detail. After hotmopping the side then more mortar and then tile. Forgetting a showerpan drain will result in countinuously moist tile grout that always grow mildew.
