Hello everyone,

I hope someone has a great idea for the layout planning of our bathroom. We are currently renovating our single-family house (built in 1950; basement, ground floor, upper floor) and find the design of the 8.7 m² (94 ft²) bathroom on the upper floor challenging. A small WC is planned on the ground floor. The bathroom will be stripped down to the shell and rebuilt (plaster removed, floor taken out). Underfloor heating is planned (floor buildup approximately 9.5 cm (4 inches)). A wall carrier system is desired. We want to do the bathroom ourselves. Unfortunately, the window and door positions cannot be changed. Due to privacy reasons, no skylight is planned.

Room size: 8.7 m² (94 ft²)
Location: Upper floor
Knee wall height: 1.22 m (4 ft)
Distance to 2m line: 0.72 m (2 ft 4 inches)
Room height: 2.40 m (7 ft 10 inches)
West-facing window overlooking the garden

Homeowner Requirements
Number of occupants: 4
1 toilet
1 bathtub, at least 1.70 m long (5 ft 7 inches) or corner bathtub if it fits; we use the bathtub about 5-10 times per year
1 shower, at least 90 cm (35 inches) in one direction, low-profile shower tray (drain integrated in floor buildup), does not have to be walk-in, single shower in the house
1 washbasin
1 towel rack
1 laundry basket
1 shower towel holder (possibly a heated towel rail)
1 trash bin
Storage space for towels and so on
1 mirrored cabinet
1 underfloor heating manifold (6 heating circuits)

The supply lines (underfloor heating, hot & cold water) come out of the floor at wall D (corner with wall A), where we also plan to install the manifold. The drain should go through wall B (corner with wall A) into the knee wall area and then into the WC below.

Design
Planning by:
- Do-it-yourself
What do you particularly like and why?

What do you not like? The shower is very difficult to place because, due to the door, window, and sloped ceiling, it doesn’t fit in any corner. Since we are about 1.82 m tall (6 ft), and this will be our only shower, positioning it under the sloped ceiling is not a good solution. In our current designs, the shower would have a lot of glass surface to dry off.

If you have to give up anything, which details/features
- you can give up: rain shower, walk-in shower
- you cannot give up:

Why is the design the way it is now? For example, process of elimination when placing fixtures, e.g., no bathtub in front of the window.

What is the most important/basic question about the layout in 130 characters?
Do you have better suggestions for fixture arrangement and wall carrier system setup?

Best regards

Just a rough 3D attempt.

Is it possible to have the door open outwards? That way, you are less likely to bump into the first sanitary fixtures.

You could also rotate the washbasin by 90 degrees, which would even allow for the installation of a 2-meter (6 ft 7 in) high wall cabinet between the toilet and the washbasin.
Ideally, a toilet should have 30 cm (12 inches) of space on both the left and right sides. I would consider 25 cm (10 inches) as the minimum. For more details, it’s best to wait for the original poster’s response 😉

Ideally, you don’t have to squeeze too much into a small room with a large window and a sloped ceiling 🙂

I based this on a room length of 2.50 m (8 ft 2 in) — 100 cm (39 in) for the shower and partition wall, leaving 150 cm (59 in), with 50 cm (20 in) for a shelf to the right of the washbasin and 100 cm (39 in) for the toilet. It’s definitely tight. I would skip the bathtub. If the shower is large, you can use bathtub inserts for the shower to manage for small children for a while. Or choose a bathtub suitable for showering.

Or maybe like this? I would use part of the knee wall for built-in cupboards with a depth of 40cm (15.7 inches).

I also have two ideas without comments, then I’m out.
