i was contemplating this exact same thing for our remodel. in the end, we're going to forego the soaker tub and just do a luxury shower. but i'm gonna include some pics here that i found in my research. fyi, check out houzz if you haven't already. that's where i've found most of my ideas and these photos. https://www.houzz.com/photos/globus-builder-contemporary-bathroom-los-angeles-phvw-vp~296757-Builder-contemporary-bathroom-los-angeles https://www.houzz.com/photos/img-2jpg-phvw-vp~3635777--2--jpg--- when i spoke to my contractor about it, he told me the problems with these is that soaker tubs require a large step up to get into it, and i'd agree looking at these photos. in this case, it may not be so practical.

Skuba, there are other options in smaller tubs. Home Depot carries the ones I am going to talk about. First there is the one mentioned above, the Bootz Honolulu. It is only $139. It is 46.5" long, 27" wide, and 15 inches high. Porcelain over steel construction. For more room and presumably better quality, there is the Kohler Seaforth that is 54" long, 30.25" wide and 14" high. That extra six inches gives you your toilet wall and extra room. This tub is sold for $1148 in white. It is cast iron and porcelain. There is also the Kohler Greek soaker tub that is 48" x 32" in Acrylic. I think it is too big in the 32" dimension for your current layout. It is drop-in, so needs a structure and tile work around it. I wonder if it would fit in the alcove where your toilet is scheduled to go. Then the toilet could have a half-wall separating it from the vanity, over where the other end of the tub was going to be. I am currently planning for a bath remodel in the only full bathroom in our house. I am toying with the idea of putting a tiny tub in my half-bath before that construction. It would give us a place to shower during the renovation (going down to the studs or further, there is a lot of water damage to be repaired in the big bath and we won't have a shower while the work is being done). The half bath is only 69" x 52", so fitting a bathtub in there will be a miracle. The reason I am considering it is that the big bath will have a wheelchair accessible shower because I will need one in the future. I had considered just making the half bath into a wet room - a shower with a toilet and washbasin in it - but there is no way to maneuver a wheelchair into that room, so the shower has to be in the big bath. So if I can fit a tub in the half bath, parents could still bathe kids there. Lascatx mentioned the one long sink with two faucets. I am planning to do that in our big bath. DH insists that we have the ability to both get ready for the day at the same time. My solution is the get the Kohler Brockway Utility sink in the 36" length with two faucets. I will either set it into an old 42" dresser I just bought for $125 (with a 6" deep ledge running the whole length behind the sink to provide more counter space) or a 42" to 48" vanity base with drawers. Here is one picture I found. I love the backsplash!

we have a 32 inch deep japanese soaking tub in the master. in the higher end homes, you're seeing more air jet tubs show up because you can use them safely with kids, and you can use products (bubble bath etc) which you couldn't with the older style water jets. i got the idea after seeing how much my girlfriends kids love the jACuzzi tub in mom's room. i'm sure ds will want to dive in ours lol but this does allow for a nice deep bathtub and contains some splashes :)

My kohler cast iron tub and cast iron shower pan in the other bathroom, both have the slip resistant finish. They can become a bit dirty, but cleans up nicely with a product I use that apparently is recommended by Kohler. Called ROG-3. I bought it online. I'm sure other products are just as good. It smells like something you could buy off the shelf in any local store. Took with my computer, so you have to read the label backwards, lol.
