Is mortar under bathtub necessary?


According to the manufacture install instructions the tub must rest on it's feet. They do not say to use any concrete additives. Make sure it is sitting on the floor and not supported by your deck. Also make sure you DO NOT install your faucet through the tub itself.
Kohler fiberglass has always been a top brand tub with thick over all construction. Follow the manufacture install anything else may void your warranty.

Really, I read the instructions and they specifically say not to drill through the upper lip of the deck tub. And install the faucet through the deck itself. So may I ask what is so funny?

To the OP : It looks like they give you two options for setting the tub.

He should have done one or the other. I would have strongly requested that he did. Since they are giving you the option for adhesive, it looks as if they don't think their tub needs the extra support, and the mortar is just to lock the feet in place.
Your two options at this point are to pull the tub and put down some adhesive where the feet are, or try to shove enough mortar under the tub to lock the legs in place. If there's no tile on the walls yet, i'd vote for option A. It really would be a lot simpler. Mark one of the feet, pull the tub... measure for the rest of the feet...squirt some construction adhesive where your marks are, and put the tub back. Furthermore, since you made the request, he talked you out of it, and now the tub is moving around, he should come back and do it, IMO.

Is mortar under bathtub necessary?


So yes, the tub is shimmed/resting on its feet. However, from my own opinion, the feet... seem somewhat inadequate compared to had mortar been used, but... it's done. It is sitting on shims, and the shims are screwed in place (from when the tub was put in place), and essentially the shim/feet are surrounded with PL glue. so although it's not "glued down", it is glue surrounded and I figured just as good?

I mean, it feels generally fine standing in it, but ... Im an over-worrier

What do you guys use to protect the tub while working in and around it?

Somebody on another thread of mine suggested it's ok to stick the front legs of a ladder in the tub to reach up for higher work... should I stick something under it? Is that safe considering the tub is on it's feet and not mortared down?

Thanks for all the help everyone.

I would not put the legs of a ladder into a fiberglass tub for fear of damaging it. I would put a cloth painters tarp over the tub and then use the cardboard the tub came in to cut a portion to line the bottom. If you want to be ultra careful, remove your shoes before enterring the tub. This will probably seem excessive to everyone else, however. One of my concerns is damage caused by tools or tiles that are accidentally dropped into the tub during plumbling or tile installation and that applies to cast iron and steel tubs as well.

Clean the tub first. Cover the tub with heavy duty plastic or a tarp. I used trash bags that I cut open so they would lay flat. Tape the plastic to the tub edge leaving room for your backerboard and tile. Tape the edge and seams so nothing can get behind it. Cut cardboard to line the bottom, sides, front, back and edge (that you step over to get in the tub).

This will protect the tub from drops and any thinset that falls. I used a small ladder type step stool to do my tile. It fit perfectly in the tub and did not damage the tub at all.

Thanks guys! Ya, If I can find something that fits in the tub, that would be great, even better if it's plastic or something. I'll have to tape it up all nice and good. I like the cardboard idea. I was thinking foam, but cardboard is probably better for the thinset spills....

I never realized that many men were so interested in TUBS.

I thought most took showers. Seems like a lot of closet soaker's on here. Just kidding to break it up. What do you think klawman, Jarhead.?

Similar question was raised in relation to a squeaky tub - you could support it with sand rather than mortar.
