Arranging a standard-sized bathroom is a challenge, but the real "stairs" begin when we have the task of functionally arranging a small toilet. This room, in large panel blocks, modern micro-apartments, or old tenements, often resembles the size of a built-in wardrobe rather than full-fledged sanitary interiors. How to fit WC bowls, a sink, a supply of accessories in an area of about 1 or 1.5 square meters, and still leave space for free movement? A very small toilet requires ingenuity, and the arrangement of a small WC must be carefully thought out in terms of every millimeter. Often the lack of a window forces us to rely solely on artificial lighting.
Although it seems daunting, at Mexen we believe that there are no too small interiors - only poorly planned ones. The key to success here is precision and the use of modern sanitary solutions, created especially for such "difficult" spaces. Remember that in micro interiors, the appropriate arrangement of a small WC, accessories, and fittings should be treated as a priority. A small WC in a block can indeed be fully functional.
Planning is key: ergonomics in micro scale
Before choosing your dream tiles, trendy faucets, or the color of fittings, you need to take a tape measure and create a thorough project of a small toilet. In the case where your challenge is a very small toilet, every decision about the placement of equipment has a huge impact on later use. Here, an error of 5 centimeters can mean that knees will hit the door, and access to toilet paper will require acrobatics. Small dimensions are not an obstacle if you opt for compact solutions.
- Movement zone: It is assumed that there should be about 60-80 cm of free space in front of the toilet bowls. In extremely small toilets, the fight is over every centimeter, so it is worth striving for at least 55 cm.
- Interior width: To use the WC comfortably and have room for your elbows, the room should be at least 80 cm wide. If your small WC is 70 cm - don't panic, but then choosing appropriately narrow ceramics becomes an absolute priority. Often, installing a sink becomes necessary to maintain hygiene in tight spaces.
- Door opening direction: This is an issue that cannot be overlooked. If the toilet is very narrow, the door must open outward. If building regulations or corridor layout do not allow this, then sliding or folding doors are the only solution, as they do not take up valuable interior space. If the room lacks a window, doors with a ventilation cutout are recommended.
Choosing ceramics: WC bowl for special tasks
A standard toilet bowl usually ranges from 48 to 56 cm in length. Adding to this the build-up of the concealed frame (about 12-18 cm), it suddenly turns out that the equipment occupies almost half the length of the room. So what to choose when every millimeter counts? Arranging a small toilet forces the abandonment of large dimensions in favor of "short" solutions. A good arrangement hides mounting accessories in the wall, gaining valuable centimeters.
Compact and short WC bowls
Compact models called "compact" or "short" with a length of merely 46-48 cm are available on the market. These few centimeters of difference often mean "to be or not to be" for your knees. In Mexen's offer, you will find hanging WC bowls that, thanks to their shortened design, fit perfectly into the definition of a very small toilet. Moreover, the lack of floor support makes the entire interior feel lighter, and keeping the area around the toilet clean is very simple. As for the color of ceramics, the safest choice is classic white.
Slim and corner concealed frames
If you opt for a wall-hung bowl, the heart of the system is the WC frame. In very small toilets, the classic one may take up too much space. Good solutions are Slim models, which have reduced installation depth. Another interesting option is corner frames - they allow the toilet to be mounted in the corner of the room, freeing up the floor center and allowing for a slightly larger sink. The design of a small toilet in a block often relies on this trick.
Limited size and micro version sink
Many people forgo a sink, believing that a small WC cannot be equipped without losing space. Quite the opposite - modern design offers aesthetic solutions that fit almost anywhere. Remember, as much as lighting is fundamental, when it comes to functionality, the sink is key. A small WC with a sink is the standard worth fighting for.
1. Reduced depth models (narrow): There are sinks available with a width of 40 cm and a depth of only 20 cm. Perfectly suited here is the arrangement of small WC accessories with a minimalist shape.
2. Side-mounted faucet: This is a clever trick that allows for the shortening of the ceramic basin itself.
3. Countertop sinks with a cabinet: The under-sink cabinet provides additional storage space for cleaning supplies. If the room is drowning in white, such a cabinet can be a subtle color accent.

The magic of mirrors and lighting: how to optically enlarge a micro-space?
Design in a small WC is pure visual engineering. Proper tricks can make even a small bathroom stop feeling claustrophobic. Lighting and a large mirror are crucial. It's the simplest way to optically enlarge the interior without tearing down walls.
Large format mirrors - your biggest ally
Instead of a small mirror above the sink, consider large mirrors across the entire width of the wall. Reflection will not only brighten the interior but allow to visually enlarge the small WC. Mirrors glued between tiles, without thick frames, create a modern depth effect. If your very small toilet is long, hanging a mirror on the side wall will visually widen it.
Layered lighting instead of central
In small interiors, one light point in the center of the ceiling is a mistake. Instead, opt for bright light from several sources. Use ceiling lights and line LED under-cabinet or floor lighting. Bright colors combined with proper lighting will make the small washroom appear larger. Since toilets often lack a window, artificial light must fully mimic the natural brightness.
Color and materials - bright colors and high gloss
There is a belief that a very small toilet must be white. Although an excess of white helps, it's not the only path to success. The important thing is to choose a stylish finish and bright colors that reflect light.
- Light colors: Cool shades of blue or light gray visually distance the walls.
- High gloss: Such surfaces act like mirrors - they reflect light, adding three-dimensionality to the WC.
- Large format tiles: Large format tiles with minimal grout create a continuous surface, minimizing visual chaos in small interiors.
- Dark accessories: To break monotony, it's worth introducing black accessories, e.g., flush buttons or sink faucets.
Smart storage - cabinet to the ceiling
In a small room, clutter significantly reduces space. A small bathroom requires every toilet paper roll to have its place. A small WC in a block will gain in aesthetics if you hide cosmetics and detergents. Thoughtful arrangement of small WC, hygiene accessories store in clever hiding places.
A furniture unit beyond the frame is a place that often goes wasted. Making a cabinet up to the ceiling allows for extra storage. Under the sink, a narrow vanity cabinet will work well. Remember that an empty floor is the best way to visually enlarge the toilet. When choosing furniture, opt for those with smooth fronts, preferably matching the wall color.
Very small toilet and heating and ventilation
In a small toilet, limited space doesn't mean giving up warmth. However, the classic radiator might be an obstacle. Underfloor heating is an ideal solution - it does not take up wall space, which often lacks room even for small windows.
If you prefer a radiator, choose a Slim model. In small interiors, efficient ventilation is essential to avoid moisture and maintain freshness, especially when it concerns guest comfort.
Accessories and additions that don't overwhelm
In a very small toilet, less is more. Instead of many trinkets, opt for functional and aesthetic accessories. Modern small bathrooms are those where the accessories are consistent with the rest of the decor. Tiles, ceramic elements, and accessories from one collection create a harmonious arrangement.
