Alcove Steel Tub Install Against a Cement Wall Questions

[GMtech]

Hi all, It’s been awhile since I have needed advice. I’m working on a bathroom remodel with an alcove tub, the bathroom is a garden view room which means it has concrete outer walls. The steel bathtub back will be against a cement wall. What is the best way to mount the 2x4 stringer to the wall, use tapcon cement screws or? The next questions are how to screw the flange to the concrete, again use the tapcon screws with a fender washers? The 1955 steel tub that was removed didn’t have a stringer and was not screwed in on any of the sides.

Thanks! Mike

Your newer steel tub may have thinner steel than your 1958 tub. If you put piles of morter under your tub, the tub will feel a lot more solid. Do not put your mortar in a slab "bed". If the concrete cannot squish, the tub cannot sit down. Multiple piles are used so that they can squish down for an exact fit. The morter hardens better if it does not dry out during hardening. You can put your piles into thin sandwich bags to retain moisture. Also, as some of the links below will point out, you would be best to have a layer of plastic under the piles.

Thank you so much for the links Reach4, very educational! The tub I was going to use is a Bootzcast which has a styrofoam base and sides to sit flat against the cement floor. The color of the tub wasn’t a true white which my daughter didn’t like, so I picked up a Kohler Villager which is cast iron and sits on 4 feet, no 2x4 stringer needed and it doesn’t need to be screwed to the walls. Hopefully a win win situation, but it weights 300lbs plus.

Im one of the few that belive a stringer isnt nessesary for a cast iron tub on the site . I think you are looking at the wrong tub they make regular white
