ᐅ New construction, master bathroom, floor plan, approximately 150 sq ft

Hello everyone,

Thank you in advance for your time and input!

The room size is 3 m x 4.75 m = 14.25 m² (32 ft x 15.6 ft = 153 ft²).

At the moment, the main focus is on the placement of the door and window, as well as the window sizes. A bathroom layout will follow later, but unfortunately, we need to finalize the floor plan with windows and doors beforehand. For this, we have to know as precisely as possible how the bathroom will be best divided. (A chicken-and-egg problem.) We need your support to determine which option makes the most sense or any additional suggestions and tips we should consider to plan the doors and windows effectively.

Below are four options that we currently find most sensible due to the openness of the room and the available movement space. The door can only be moved as much as shown in the attached sketches.

The two of us adults mostly use the shower, so the focus is on a nice, large shower rather than a bathtub. However, we still need a bathtub for the kids for some time. (Household of 5 people; an additional guest toilet and a small extra bathroom are planned.)

We have often heard about zones in the bathroom—perhaps someone could also explain what exactly is meant by zones and how this could be implemented in a 14 m² (150 ft²) room.

To the north, we have a beautiful view, so it would be a nice-to-have to place a larger window facing north.

We look forward to your input and new ideas!

Thank you very much in advance!

Best regards

I would recess the door and, if possible, have it open outwards.
Instead of a large east-facing window facing the neighbors, could you install a roof window? A roof window in the bathroom is great. On the east side, then only a small window for ventilation.

Apparently, you like "freestanding" bathtubs. I definitely would not plan for that. It only creates awkward corners for cleaning behind it. Even a 14 m² (150 sq ft) bathroom is too small to make a freestanding tub really impressive. You’d need a luxury mansion for such a tub to really stand out. A large shower is always a good idea; it can be designed without doors, so there’s no need for maintenance.

“Zoning” is just a modern term to describe sensible planning: avoiding walking across the whole bathroom with wet feet to get to the toilet, dividing the bathroom into “zones” so multiple people can use it at the same time.

14 m² (150 sq ft) is actually not small for a bathroom. You can fit everything you want plus some free movement space. That won’t be a problem.

Planning a bathroom without considering the floor plans makes little sense. Where are the possible drainage pipes located downstairs?

A view can sometimes also mean looking inward.

What does the architect say about the bathroom design?

Window planning is also coordinated with the other windows on the facade.

... exactly, the wastewater pipes of the house, possibly in the floor below.
It’s not necessarily a chicken-and-egg situation, but the process should go from rough to detailed planning. What’s stopping you from joining the floor plan discussion here

Hello everyone,

Thank you for the feedback.

I would recess the door and, if possible, have it open outwards.

Recessing the door is rather inconvenient for the rest of the floor plan. Opening the door outwards is possible.
Is recessing meant to gain more space inside the room?
The door can be moved within an area of 155cm (61 inches) at the bottom left (see sketch below).

Apparently you like "freestanding" bathtubs. I would definitely not plan that. It only creates difficult-to-clean corners behind. Even a 14 sqm (150 sq ft) bathroom is too small to make a freestanding tub "impressive." You’d need a mansion to make such a tub stand out. A large shower is always good, as it can be doorless and requires less maintenance.

This is due to the modeling in the design software. We definitely do not want a freestanding tub. The idea was rather to extend the wall behind the tub to create storage space. So more of a "built-in slanted bathtub."

A view can sometimes also mean a view into the room.

We are building on a hillside. From the window, at most a neighbor from a downward angle can see inside.

What does the architect say about the bathroom layout?

The first version on the far left is what we have planned so far. The architect agrees that it works well. More detailed planning will be done in the bathroom design phase. After that, we can only shift the windows slightly.
The window sizes now need to be defined, among other things, to calculate the structural requirements.

Window planning should also be coordinated with the other windows on the façade.

That is being done as well. Below is an image showing the alignments with the lower windows. This will be considered as much as possible.

Where are the wastewater pipes possible at the bottom?

The wastewater pipes will be routed downward at the two eastern "corners" (black squares). (See upper sketch)

What’s stopping you from joining the floor plan discussion here?

Thanks for the suggestion, we might consider it.

The main goal of this discussion: Is any of the above-mentioned options or another good enough to install a larger window on the north side (180cm (71 inches) instead of 100cm (39 inches) wide)?
Advantages would be a better view, although I wonder how often one would actually use that?
Another advantage would be more natural light in the room.
If in doubt, we will go with the smaller window and be more flexible with the room layout.

Further questions:

• Is it acceptable to walk directly towards a shower when entering the bathroom?
• Regarding option 2: The toilet is centrally located. Is that a problem?
• We plan a double sink 160cm (63 inches) wide. How much clearance should be left on the sides? How much space should there be towards the door?
• Is a passage width of 130cm (51 inches) behind the sink enough to get from the door to the rear area of the bathroom?

As recommended, the discussion has been posted in the floor plan design section.
