ᐅ Incorporating a Larger Shower into the Floor Plan – What Size Should You Choose?

Thank you, Alex! That sounds good. It will probably fit in my bathroom.

If I want to build up one side of the shower, how thick would such a wall be approximately? The wall is not ceiling-high, but up to 200cm (79 inches). Glass blocks are 8cm (3 inches) thick.

As a rule, you can usually build this with an 11.5cm (4.5 inch) masonry unit, or possibly use an 8cm (3 inch) aerated concrete block. The important thing is that the wall is securely anchored within the existing wall. Additionally, you have to consider plastering compound, possibly render, and of course the tiles. So, I would definitely plan for a total thickness of 10 to 13cm (4 to 5 inches).

We have the width of 1.20m (4 feet).

Inside the house, we are now planning 120x90.

Oh, 13cm (5 inches) would be a problem, 10cm (4 inches) might still work. Maybe glass blocks after all? Would they provide a fully functional shower wall?

This depends not only on the side you enter from but also on the side where the mixer tap is installed. Having the larger dimension where available space is reduced by fixtures doesn’t make much sense. In terms of floor area, 80/100 is equivalent to 90/90.

They actually come in different sizes, or are you referring to specific ones already planned for this building?
I wouldn't choose them because of the joints.
My preference would be to ask if the partitions (for example, for concealed cistern installation) can simply be built-in. That might result in a finished thickness of 10cm (4 inches), which corresponds to half the width of a 20cm (8 inch) tile.

The bathroom is quite small (220 x180).

Have you considered a shower enclosure with a rounded corner?
Depending on the surrounding space, that might fit better...

Glass blocks were just an idea: they let some light through so I’m not standing in the dark in the shower. The planned wall separates the shower from the washbasin, which is directly adjacent on the other side of the wall. I would prefer not to design the room length greater than 180cm (70 inches). I’m calculating 90cm (35 inches) for the washbasin, 80cm (31 inches) for the shower, and 10cm (4 inches) for the shower wall.

A glass partition would also be possible, but I imagine it would be awkward because of the washbasin directly next to it.

If I go with a shower wall, it has joints just like a glass block wall, right? Or is it about the number of joints? After all, the tiles are twice as large as the glass blocks.
