Walkin in shower with a seat??
That's the route I'm taking. Got it framed and walled, need to get busy on the tile.
Build seat out of brick and mortar, tile over the brick.
I don’t recommend this. A house gets tired of holding up the additional weight over time and the floor joists sag cracking the water proofing. A better method is a Schluter bench or several other pre made shower benches. Houses built in the 50’s-70’s are particularly susceptible as longer floor joist spans were common. In fact we abandoned the old mud beds and backer boards completely and only use the Schluter system. Other companies have now competing products.
