The 2022 Separett Villa Extend is the replacement name for the Villa 9020 (see our blog post).

The Separett Villa Extend is a urine-separating waterless toilet that requires a solid waste container beneath the floor (not included – see Villa Extend Accessory Kit). The solids container should be reachable from the outside. It is suitable for anyone looking for a higher-capacity and user-friendly solution for your cabin, cottage or tiny house that has a raised floor and prefers external collection/emptying of solids and increased solids capacity.

Based on the proven urine-diverting design of the Separett Villa, the Villa Extend differs in that it has a ‘chute’ to direct solids through the base of the toilet into an external solids container which would be located under the floor (with external access). The benefit is that the solids container can be of a larger capacity, providing longer operational time between emptying. The external container would also be suitable where building regulations prohibit carrying of solid waste through the living area of a dwelling.

Particularly suitable to new-build cabins, tiny houses, cottages or houses where the floor has a void underneath. You can supply your own solids collection system, or for ease of installation, you can purchase the Separett ‘Solid Waste Collection Kit’ designed specifically for the Villa Extend.

The ‘chute’ should ideally be connected to a pipe with an internal diameter of 150mm.

The Villas design, pioneered by Separett, separates ‘solids’ from ‘liquids’ using a urine-diverting toilet bowl, and the fan/ventilation system draws foul air from the toilet to eliminate odours efficiently and completely. When the user sits down, a special concealing screen automatically opens, revealing the solids container which is normally hidden from view.

Urine is collected in the front part of the urine-diverting bowl and it then flows, with gravity, out of the rear of the toilet and into either a small external soak-way pit or a container for subsequent emptying (container not supplied).

Unlike many other compost toilets, the Villa does not need any sawdust or cover material, making it extremely easy to use and maximising the capacity of the solids container.

The toilet itself is made from a type of high gloss plastic, called polypropylene, similar to shower trays and baths. This material is highly durable, fully recyclable, impact-proof and easy to clean using non-abrasive cleaners, maximising hygiene.

For those with small children, or those likely to have small children use it, there is an optional child seat that is easy to attach and reattach as needed and ensures kids can use the Villa in the correct way.

Separett Villa installation requirements

  • Electrical: The Separett Villa will require either a 12-volt DC supply (such as a leisure battery and solar system) or an adjacent 230v AC mains socket in order to operate the fan. The fan runs continuously to provide 100% odour-free operation.

  • Ventilation: The fan pulls air through the toilet and out through a 75mm vent pipe at the top of the toilet. From here it can either be turned through 90 degrees and go directly outside through the wall (recommended), or straight up and through the roof/ceiling. The outside part of the duct is finished with an insect screen and a cap (included with the installation kit). For ventilation options, see this page.

  • Liquid outlet: The 32mm urine outlet is on the rear of the unit and can be led to a domestic greywater drain, a soak-away or a holding tank. Please ensure you comply with any local regulations regarding the disposal etc of urine.

  • Suitable solids container under the floor (with easy access to the outside). A Separett ‘Solid Waste Collection Kit’ is available as an optional extra.

Solar & Battery recommendations

If you are looking for a solar panel and battery to supply power for the Villa in an ‘off-grid’ setting, we can only make general recommendations as the specifics of your site and other local conditions will affect how much electricity a solar panel is able to generate. Assuming a site in the UK, and that your intended location doesn’t have any significant shading or shadows during the day, and with the solar panel angled due south, we generally suggest a panel of around 50 watts, coupled with a 50Ah battery is fine for year-round use.

Included accessories:

Most items are included with the Separett Villa to enable a typical installation where you vent through the wall behind the toilet. In addition to the toilet itself, you will also receive: 40cm length of vent pipe (Ø75mm), external vent grid/cover, indoor flashing for vent pipe, 2m semi-flexible hose for urine waste (Ø32mm), connector pipe 90°, vent cowl, power cable/mains adaptor, and mounting screws,

For details of possible ventilation options, please see our blog post: Separett Villa Ventilation Options.

Please note that the manufacturer may change the specifications, design and supplied accessories as part of continuous product improvement.

  1. John

    It works fine and it’s easy to install.

  2. Stuart Hatton

    It’s good, the only thing is that they’re a nightmare to clean when people use them incorrectly. If some of the internal parts were placed differently it would be better. I had an issue with a couple of missing parts, but I was impressed with how quickly the issue was solved by WooWoo.

  3. John Sterland (verified owner)

    Very nice piece of kit.

Delivery to a non-UK address? No Problem!

Since Brexit, the process of selling to non-UK customers (including those in Ireland!) has changed but we don’t want our customers to pay more so we are offering to refund your customs duties and admin fees.

VAT generally evens itself out
You will find that our price is reduced when selling to non-UK countries. This is because we don’t charge UK VAT (20%) if a customer wants their toilet sent to an address outside the UK.

Instead, the customer will be requested to pay VAT on the import once the package enters its destination country. Across Europe the VAT rate is usually also somewhere around 20% so the saving made by not paying UK VAT is generally evened out by having to then pay local VAT when the package enters its destination country.

Customs duty/admin fees
You may also be charged customs duty and in some cases even an admin fee when the package crosses the border. If this happens, make sure you keep your receipt so you can forward it to us. When we receive your receipt, we will refund these extra fees back to your account.

In short…
Our non-UK based customers shouldn’t have to pay more for their products than our customers in the UK.

If you’re unsure about anything, please don’t hesitate to get in contact with our friendly team.
