I am putting a Westlake model Eljer tub in. Just did exact same tub in a different bath. When you step inside the tub like to take a shower it feels like it is flexing and not solid even tho it is a steel tub,,,,directions say no further support needed.
Maybe cause the house (old) was a little crooked and we used what we had. Tub drains okay BUT just not as solid as I would like. Can I set THIS new tub in a mortar bed of thinset??? or other mortar?you tell me if there is any way to absolute support tub floor to make it "SOLID as a rock???
Related issue I measured floor to bottom of lip where 2 X4 gets mounted on wall for support and drain end of tub is 1/4 inch more than foot end of tub...seems like it should be other way around and tub bottom should set directly on solid subfloor!!
