ᐅ Bathroom Renovation 12 sqm – Ideas for a T-Shaped Layout – Is There Enough Space?

Dear community,

We are currently planning the renovation of a single-family house built in 1974. As part of this, a new bathroom will be created on the upper floor by removing an interior wall, resulting in a space of approximately 12sqm (2.73m x 4.485m [9 ft x 14 ft 9 in]).

I would really like to install a T-shaped layout. Unfortunately, I have no idea what minimum or recommended dimensions should be followed to ensure comfortable passageways, splash protection, clearances, movement areas, etc.

For the fixtures, we would like an open shower, a toilet, a double vanity, and a freestanding bathtub (at least 1.70m x 0.80m [5 ft 7 in x 2 ft 7 in]).

Do you think this will fit well?
How long should the shower wall be at minimum to prevent water from splashing out completely? How wide should the toilet privacy screen be to allow comfortable use? How wide should the passage (distance between the bathtub and the shower wall) be at minimum for easy access?

Do you perhaps have alternative suggestions for the layout? I am open to any ideas 🙂

Thank you for your advice.

What are the window sizes and the sill heights? How far is the door from the corner?

This can all work like that.

All of that can work like this.

Large window: 131.5 x 77 cm (52 x 30 inches). Sill height: 134 cm (53 inches) — so a narrow, tall window with enough space underneath to place something.

Small window: 57 x 72 cm (22 x 28 inches). Sill height: 137 cm (54 inches).

Distance from door to corner: 16.5 cm (6.5 inches).
Door width: 84 cm (33 inches).

Best regards

Bathtub directly under the window?

Where should the drainage go? What is underneath there?

Yes, I wanted to place the bathtub directly under the window – is there any reason not to?
The drainage needs to be completely redone, and the screed, etc., will be renewed.

What is located below this room? Drainage has to go somewhere, after all.

Creating a separate thread for every single change, each showing only a partial view of a room, isn’t very effective. A house is, after all, a system where everything works together.
