Conversion from tub to shower thoughts

Ive recently had to tear the walls of my shower out due to the tiles were starting to fall off the wall and i noticed the tub flange is rusted out so i have to make a decision to just put another tub in or just buy a shower base and go that route.. but the issues i see is that drain which is of course a 1.5" drain and the bases require a 2" i'm going to assume its just going to be easier and keep costs down by just replacing the tub ive read some people have used some sort of reducing bushing to make the drain work.. from what i can tell the drain has a steel pipe and don't really want to mess with any of that trying to keep costs down.

Welcome to the forums!! It doesn't make sense to me, either, why a tub with 40 gallons of water rushing out of it only requires a 1 1/2" drain, while the trickle of a shower requires a 2" one. But we don't make the rules, do we??

Unless you can replace the entire drain with 2", you may be relegated to replacing the tub with a 1 1/2" drain set up. Wish I had better news, but necking down the drain is not an option.

an 1-1/2" by 2" fernco or a "no-hub" transition coupling will help making the connection from steel pipe to pvc or abs

Because a tub has a 18" plus skirt and can hold more water. It can drain at its leisure.

A shower has say 3" or so skirt and needs to drain faster so overflow does not occur.

A tub has an overflow also... Shower not...


Make sense?

Makes sense, Mike. It just seems an industry standard of 2" for both tubs and showers would make even more sense.
