yes its water proof........ people even use Masonite board which is not water proof
15-16 inches from back wall. 8-10 inches from side wall tub drain is on. Measurements are to center of tub drain hole. Measurements are close, not exact, and are for a standard tub.
depending on how large your hot tub is, you can just use a pool shark. they plug into the wall, and move around the bottom of the pool, or hot tub if you like. they are really neat, they are basically underwater vacuums.
Most of them are in the wall. The other would be a deck mount, which is mounted to the fiberglass tub deck and uses a Roman Tub Faucet.
The width of a standard American bathtub is between 32 and 42 inches. The size will really depend on what material the tub is made from and whether or not is a wall to wall or a corner tub.
I would first pour several buckets of water down the drain without running the tub faucet to see if the drain is leaking. Then I would with a spray bottle direct water around the drain lever/overflow plate, tub spout and valve to see if that is where the leak is. I would then move to the valve itself to see if that is leaking checking packings and the diverter. If nothing shows at that point check tub tiling and possible water spilling on the floor. If water is appearing and you cannot determine where it is coming from you may have to open a wall or ceiling to determine. I also try measuring where the leak is and comparing the measurements to locations of tub parts. In any case I try my best to find the cause before cutting walls and ceilings unless the ceiling is already shot from the leak then open it up and look. Wall openings are done on the wall behind the tub valve usually a closet or bedroom wall, never break out the tub wall around the valve.
Probably because the hot water pipes are right behind the front wall of the tub.
It depends on the width of your tub. The distance would be so that your shower curtain would hang in the middle of the edge of the tub.
"Standard tub" is too vague. More information is needed, especially what the 'tub' is used for? Tub of icecream? Tub of lard? Bathtub? etc.
it is a metal tub used for washing.
You generally have to cut a hole in the wall behind it.
