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

First of all, a like for your detailed comments and information.
This is almost a template for many who are a bit careless in this regard.

only shower in the house
1 washbasin

Two questions:
Is there another bathroom in the house? At least a toilet and washbasin?
Where is the downpipe from the drain?

Otherwise, I find your requirements quite ambitious: a bathtub with the minimum size for 5-10 uses per year, so it shouldn’t be placed under the window, towel radiator...
The heating circuit manifold can’t just be installed anywhere either. But I only just read that it should be placed on the left side of the plan.

1 bathtub at least 1.70 m (5 ft 7 in) long or a corner bathtub if it fits; we use the bathtub about 5-10 times a year
1 shower, at least 90 cm (35 inches) in one direction, shallow shower tray (drain in floor construction), no need for a walk-in floor-level shower, only shower in the house
1 washbasin
1 towel rail
1 laundry basket
1 shower towel rail (possibly heated towel rail)
1 trash bin
Storage for towels, etc.
1 mirrored cabinet
1 underfloor heating manifold (6 heating circuits)

With all that listed, and with all due respect: for 4 people, I would rather prioritize having at least a bit more free movement space than including a laundry basket, which could easily be placed elsewhere anyway. Towels could also, if necessary, be stored on a shelf above the door or in the wardrobe.
If certain things are essential, at least no standing surface should be sacrificed to such unnecessary items. What’s the point of something that you keep bumping into?

Well, these are just my thoughts. Personally, I would just shower in the bathtub 🙂

I suggest a somewhat softer and more ergonomic design so the bathroom doesn’t feel overcrowded.
Toilet towards the drain, bathtub sized about 90 x 160 cm (35 x 63 inches) can be a bit deeper, shower open and airy without walls.
The manifold moves into the continuous pre-wall, an asymmetrical washbasin (unfortunately I only have a sharp triangle shape), cabinets under the window. That’s what you had in mind too, right?

How about something like this?
A stud wall along the 2 m (6.5 ft) line, using the space above the toilet and sink for built-in cabinets?

I actually think it looks nice, but it will get very tight around the toilet and washbasin.

You could also rotate the washbasin by 90 degrees and then potentially install a 2 m (6 ft 7 in) tall wall cabinet between the toilet and washbasin.
