***update***
OK, it's been awhile so I'll give an update and ask my question(s)...
Tear out is done.
Plumbing & electrical done.
New tub drain
old plumbing supplies/drains capped
2 recessed lights
1 bath fan
30 amp dedicated electric supply to whirlpool
Rough-in inspections passed.
Now, plumbing for the new whirlpool tub (which required 'flipping' the tub, grrrrr) necessitated pulling up a 7'x3' section of my 5/8" T&G subfloor. When replacing this section, I think I inadvertantly put the new section in 'upside-down' meaning that the ink marks on this section of plywood are showing.
I will be going over the entire floor with 1/2" ply laid (overlay) perpendicular to the subfloor...screwed 4" on edge and 6" in the field...
Here's my concern: The new section of subfloor is about 1/16" lower than the existing. Will this cause my 1/2" overlay to pull up in that area? This area is UNDER the tub (will be mortared in) and UNDER the new shower pan (which will also be mortar). Should I consider feathering-in some floor leveler at the joints?
Will this be a problem for me down the road, or do I have nothing to worry about here???
Thanks!
Walt
