Double Open Shower Fall With "Tile Over Shower Base" on Timber Floor

Hacking together two shower bases like that is probably more effort and much less reliable than just getting a custom one that does it right, fully sealed with the correct fall across the whole shower pan area.
The red area will need fall towards the grate/s (and away from the door) so you'd need to account for that in your modifications. How good are the joins going to be long term?


Google custom shower pan bases and you'll find there's heaps
Depending on your dimensions you might even find one off the shelf that'll slot in. (Check if they require added noggins for additional support.)

It might be better to have the drain in the centre away from both the showering areas. Also away from the entrance towards the rear so pooled water isn't near the door.

** Given that you've ripped out your flooring, it's a good opportunity to put down Scyon /similar onto your joists for your wet areas.

Thanks so much for the response.

Yeah sorry, I actually meant timber floor as in that's what the floor was and it's a joist floor with flooring on top.

I am putting Scyon down in the bathroom and toilet.
The shower base is designed to put down, and then butt the Scyon against it.

If there's going to be splash in the middle and it cause an issue, then I'll take a look at the custom bases.

If that is too expensive, would 900 x 1200 bases x 2 work?



Or does there need to be slope/fall the whole way through?

Just form the falls in the framework and Scyon the entire area.
