Campervan Toilets Specialists

Installing a toilet seems simple until it isn't. While a basic porta potti just needs a secure spot, a fitted cassette or composting toilet requires absolute precision. A professional installation guarantees watertight seals around the floor and walls, preventing slow leaks that rot your van's structure from the inside out. Pros also handle ventilation correctly, cutting a discreet, weatherproof hole in the van's body for an extractor fan or vent pipe. This is non-negotiable for composting toilets to eliminate odours. In practice, this means you avoid the costly nightmare of fixing water damage and a lingering smell that no amount of air freshener or the best toilet fluid can hide.

When vetting a specialist, ask specific questions about their process. Enquire how they seal the shower tray or floor penetration and what materials they use. For composting models, ask how and where they will install the 12V electrical systems for the fan and external vent. A good builder will explain their method for securing the unit so it withstands rough roads. Vague answers are a major red flag. For most Transit-based builds, expect a cassette toilet installation to take one or two days and cost between £800–£1,500, including the unit. A more complex composting system often requires two to three days, with a final price tag of £1,500–£2,500 depending on the model.

Finding the right installer used to be a gamble. CamperBrain simplifies the search by connecting you with vetted conversion companies. Instead of relying on a single quote, you can browse portfolios to see examples of their previous bathroom and toilet installations. This allows you to find specialists with direct experience in the exact system you want, whether it’s a Thetford cassette or a high-end composting unit. As a result, you can read detailed reviews from other van owners, confirming the builder's skill in creating a functional, leak-proof, and long-lasting toilet solution. You hire them based on proven results, not just promises.
