TROBOLO TinyBlœm

The Verdict

Fully odor-neutral, at a premium price

With its compact dimensions, the TROBOLO TinyBlœm is among the smaller stationary composting toilets and is ideally suited for tiny houses, motorhomes, or any room with limited space.

With its compact dimensions, the TROBOLO TinyBlœm is among the smaller stationary composting toilets and is ideally suited for tiny houses, motorhomes, or any room with limited space. It measures 48 cm (18.9 in) (H) x 37 cm (14.6 in) (W) x 49.5 cm (19.5 in) (D) and weighs around 11.5 kg (25.4 lb). The seat height is 45.5 cm (17.9 in), and the load capacity of up to 200 kg (440.9 lb) is more than generous.

Thanks to its low weight, it can easily be relocated if needed, as long as it's not firmly anchored, which, however, is necessary and also recommended for the final installation, especially in mobile setups.

The combination of a sturdy wooden housing, compact design, and integrated exhaust solution makes it a particularly practical choice for small spaces.

Assembly

The TinyBlœm composting toilet is delivered pre-assembled and ready for immediate use, which is a big advantage over many DIY kit solutions. The actual assembly essentially consists of screwing the toilet firmly to the floor. This is mandatory, since without anchoring it could tip over or shift while sitting.

The mounting points are clearly accessible, though, and the low weight made assembly and precise positioning of the toilet much easier for us. The integrated exhaust system is also already built in, so you only need to route the exhaust hose outside and connect the power supply (USB, 12V, 24V, or 230V).

Overall, the TinyBlœm is a good choice for people who want a fixed installation in their bathroom but don't have the time or desire for a complex assembly process.

Material and workmanship

One particularly strong argument for the TinyBlœm is the material: the housing is made entirely of multi-layer birch and alder wood, which is oiled and cleanly sealed. This gives the surface a pleasantly smooth feel, and you won't get accidental splinters where you least want them.

The wooden seat is also carefully finished, which looks very high-quality and is also functionally convincing, since any urine splashes can be wiped off just as easily as with a classic toilet seat.

Despite its low weight, the body conveys surprising stability. The urine diverter and containers are also precisely fitted and give a sturdy impression. The separator reliably ensures that liquids and solids are kept apart. This makes both use and hygiene easier and prevents odors.

Comfort

The seat height of 45.5 cm (17.9 in) roughly matches the dimensions of conventional toilets, so you don't have to sacrifice comfort here. As a result, using it feels familiar. The wooden seat is also a pleasant surprise: it's ergonomically and comfortably shaped and remains comfortable even during longer use.

As with all composting toilets, use must be done while seated. If you stick to this, the separation works cleanly and reliably. This keeps toilet use uncomplicated and hygienic.

The solids container is easily accessible and can be removed without much effort. Especially in a tiny house or motorhome, where processes should be as simple as possible, this is an important plus.

Odor development

In terms of odor development, the TROBOLO TinyBlœm performs particularly well, because two systems work together here to reliably prevent odors. First, the clean separation of solids and liquids means unpleasant smells barely have a chance to form. In addition, the TinyBlœm diverts urine directly outside via an external line, meaning there is no urine container inside the unit at all. This means no liquid that could smell at all collects inside the composting toilet's body, further reducing the typical sources of odor.

Second, the TinyBlœm has an integrated exhaust system that continuously creates a slight negative pressure and reliably vents any developing odors outside. The fan operates quietly and energy-efficiently, so the interior remains permanently odor-free even with regular use and hot temperatures. In this model, the combination of external urine diversion and exhaust system replaces the SafeShell System, which serves as a reliable odor seal for the urine container in other TROBOLO models, such as the SilvaBloem.

Value for money

The TinyBlœm is priced in the upper segment, which we consider justified, however, given the high-quality woodworking, the compact construction, and fully odor-free use. For anyone with limited space who doesn't want to compromise on material, workmanship, or odor neutrality, the TinyBlœm offers a very well-rounded and reliable overall package.

Our conclusion

TROBOLO's TinyBlœm composting toilet impresses with its simple assembly, which is also easily achievable for less experienced users. The good workmanship and effective separation system left a particularly positive impression on us. The elegant design and compact size also particularly appealed to us.

Points are deducted for the high price, which, as suspected, results from the effort involved in manufacturing this toilet to achieve its appealing design. Because although the TinyBlœm represents a compact and visually appealing solution for small spaces, there are composting toilets that don't perform much worse in terms of compactness and offer a lower price. For users looking for a more affordably priced composting toilet, we therefore recommend the TROBOLO TeraBlœm composting toilet, an equally sustainable solution specifically for indoor use, whose design is simpler and whose price is accordingly lower.
