Shower plumbing

[SHELCO]

I have a commercial building that has a old bathroom that we want to add a shower in. My question is we removed the toilet that will not be reused. Can I install a standup shower over the toilet flange? I checked out the piece together units in home depot over weekend. quite simple to install with base etc.
I am sure its not up to code.. neither is the rag jammed in the flange now Is there a adapter that will allow me to accomplish this?

Toilet has the p-trap built into the fixture so not in your groundwork’s/ plumbing rough.

A shower usually has a 2” line with a p-trap. Your toilet is likely 3 or 4” and no trap.

Sorry can’t help more than this.

Can you get under the flange, or is this on a slab? A toilet flange does not include a trap, as it is expected for the toilet to provide one. A shower expects a trap under it.

If you have the height, I suppose you could build a platform under the shower for a trap to fit into the toilet drain, but the better way would be to remove the flange and connect the trap directly to the drain.

It is on a slab. I could easily make a pee trap if I could find a adapter that would bolt on to toilet flange.
I guess the shower would be 8-9 inches off the ground, which is no big deal
Thanks!

Bolt to the flange, no. But if the pipe is PVC under the flange (and not a lead bend), you could use a rubber Fernco push-in bushing.

I'm no plumber, but personally, I'd do it. How I'd do it is "elevate" the shower floor enough to be able to access the plumbing and install a P-trap (if necessary). I'd make sure I had an "access panel" if I ever needed to get under there. Up to code? I have no idea. Handicap accessible? Probably not.

You can do some really cool things with moen diverter valves to make quite the fancy shower (mulit-head) for not that much money..

I would not be giving up a toilet, I would put the shower pan on a pedestal with an accsss and drain the shower into the toilet vent stack.

My advice is guaranteed to be worth exactly what you are paying me for it.

its a 60 year old cast pipe that i will be attaching to

Stepping up and down 9" to get in or out of a wet shower feels like a slip and fall waiting to happen. If you do it, set it up carefully.

No desire to cut the slab and modify the plumbing?

Aren't those made to fit in a hub?

I suppose ya could get another toilet flange and bolt that to the current one. Going to need some steps.

You are going to need some horizontal distance from the shower trap to the closet flange to allow sufficient trap arm length to avoid creating an S trap. A toilet is by definition an S trap.

We do about 20 showers a week and would trench the slab to install this.

I believe they come in different sizes, but yeah, a hub would be the most common use.

You can add as much horizontal distance as you want, unless you install a vent it's still an s trap.

True, so you need to dig up the closet bend and connect horizontally to the lateral from the toilet or run above the slab and add a vent.

Our previous house had had the basement finished before we bought it. I have no idea what was under the raised shower but I wasn't happy w/ the step up from a safety standpoint. So I got an outdoor mat something like this.

What is a hub?

The bell end of old cast iron plumbing.
