Mirrored walls with LED, custom-made shelves, and enough ingenuity to make the best use of niches and angles – for bathrooms with sloping ceilings, it takes a little creativity to achieve an optimal spatial effect.

With our tips, we will show you which design options for the rooftop bathroom are particularly advantageous and how you can tackle and master the bathroom’s challenges with sloping ceilings through well-thought-out space planning, light, color, matching cabinets, and shelves.

Tip 1: Plan Room Design in Advance

If you can design and create your bathroom, you have many options when planning to conceal the lack of room height in the attic bathroom. First, determine what room heights and what you want to accommodate in the bathroom.

When dividing up the space, make sure that there is a sufficient room height of at least 2.20 meters in the bathroom so that there is the necessary space for the shower and standing area in the tub in the attic bathroom. Also consider the statics due to roof beams, dormers & Co. Skylights are an excellent light source and should therefore be installed as high up and as large as possible.

A shower under the sloping roof is possible but requires a bit of finesse. Instead of a shower curtain or masonry, a transparent glass wall is charming here, dividing the space without visually diminishing it; you should hire a glazier for glazing under a pitched roof.

Plan for a standing height of at least 1.90 meters above the washbasin – this is a comfortable height for most people to get ready in front of the mirror. For example, you can build the vanity to the side of the sloping roof. If there are too many slopes in the way, it may be useful in the planning to put in drywall, which will straighten the slope of the roof and serve to install the sink or vanity in the bathroom.

For the toilet: depending on the roof’s slope, you can make compromises if necessary. If the slope is 45 degrees, the toilet may be placed quite close to the wall. If, on the other hand, the slope is smaller, make sure that there is a room height of at least 1.45 meters above the toilet. Here, too, you can help with drywall – and at the same time, conceal the cistern.

A good decision is to place the bathtub directly under the roof slopes and skylights. This way, you not only enjoy a view of the sky, but the lack of room height also causes little disturbance when lying down.

Tip 2: Custom-Made Products Are the Trump Card

For sloping angles and corners, you can hire a carpenter to fit custom-made shelves and cabinets under the slopes in the bathroom: This usually looks better than a multi-level shelf from the furniture market and makes more efficient use of the available space.

Tip 3: Use Storage Spaces

Corners and niches are often seen as a problem with rooftop bathrooms. However, the trick with sloping ceilings is to use them efficiently for storage and room design. With creativity and craftsmanship, you can install small wall shelves in niches, for example, to place towels, bathroom utensils, or stylish decorative elements – this also applies to the height.

Suppose the small bathroom under the roof does not allow high cabinets, and you lack storage space. In that case, it may be advantageous to install wall shelves in height – the better they are dimensionally adapted to the local conditions, the more you can accommodate.

The knee space, i.e., the vertical wall area below the sloping roof, can be used with elongated sideboards. With a few steps, you can build a knee-floor shelf yourself.

Tip 4: An Adapted Lighting Concept

To counteract the sometimes cramped feeling and darkness of a bathroom in the attic, think specifically about light when designing the bathroom as early as the planning stage. You can capture a lot of daylight by using huge windows. In this way, you can already ensure an optimal supply of light when planning the room.

Have you decided on the floor plan and room concept, or are you just renting? Then artificial light sources are the way to go: For example, work with ceiling and floor spotlights, light rails or spotlights on the slopes of the roof or beams, and LED-lit mirror surfaces or mirrored cabinets. Always combine direct and indirect light sources.

How much lighting is needed? As a rough guide, the total luminous value of all lamps combined should be between 4000 and 8000 lumens.

Decoratively illuminate niches and dark corners with spotlights and light spots. If you use lovely furnishings in the bathroom, you can use light to highlight them and visually enhance the sloping roof.

Tip 5: Mirror Surface Creates Space

Large mirror surfaces, even in small bathrooms with sloping roofs, create space and width. So use mirrors purposefully to make the rooftop bathroom look bigger. If you use a complete mirror wall instead of a round or rectangular mirror above the washstand, you will emphasize the room’s advantages in a sloping roof.

Mirror walls are available both as ready-made modules and custom-made ones. Thus, above the tiles, you can even decoratively line triangular wall surfaces with mirror glass.

Tip 6: Use Colors and Tiles in a Targeted Manner

Light colors on the ceiling and walls are advantageous to enlarge small bathrooms under the roof visually: If white is too boring, you can use light gray, blue, or cream to create delicate color accents. Dark shades, on the other hand, make the room look smaller.

By the way, the same principle applies to tiles. Here, you can create a certain spatial effect with the color and shape: elongated metro tiles arranged in a semi-bond suit of a rectangular bathroom section. Narrow, elongated bathrooms benefit from square tile formats.

Tip 7: Insulation and Soundproofing

Thermal insulation and insulation deserve special attention in the attic bathroom: for example, the bathroom should be resistant to moisture and have insulation between the rafters. Of course, if there is no insulation, you can install your insulation, but this will cost valuable living space.
To prevent noise from pipes and drains, you would be wise to invest in soundproofing, especially for attic bathrooms, so that the bathroom under sloping ceilings is not only a cozy warm place but also calm and quiet.
