The Pent House is a very versitile design with up to 2 toilets and 1 urinal in a single unit.


As with all of our units at Reworkshop the Pent House is built from a whole host of sustainble materials Including recycled pallet and scaffold timber,  recyled plastic fittings and sheet materials and FSC timber .


The Double Penthouse offers two composting toilets and the option of a lean-to urinal.

The toilets are fitted with separators which pipe urine away to either a soak away or drainage . You can choose either an IBC container or two, 240litre whellie bins for the solid waste collection.

When you opt to use twin wheelie bins each unit will be fitted with a sawdust container with hinged lid beside the toilet, this option isnt availible with the IBC.

When opting for the IBC we also install a ventilation flue from the bottom of the IBC to above the roof line which helps aerate the humanure aiding composting. this isnt availible with the wheelie bin option as it isnt really nessary with the smaller containers.


The Single Penthouse offers one composting toilet utlising a 120litre wheelie bin for solid waste collection and a urine separator which pipes urine into either a soak away or drainage.

The single Penthouse also has a sawdust container with hinged lid fitted.


If you would like to fit handbasins or would like to customise the Penthouse to suit your needs please dont hesitate to get in touch.


The Penthouse is a large heavy structure therefore it can not be shipped, we deliver and install these in person. Prices for delivery & installation vary depending on your location, please see the attahced map, prices for areas are listed below.

While this is a fairly large structure it is classed as temporary, and both the single and double Penthouse can be moved with pallet forks without the need to dismantle them.

The height of this sturcture means it can be suseptable to wind so we suggest a sheltered area, however we fit storm lashing eyelets on all four corners incase they are required.


Below our delivery & installation prices are listed for each area. Included in these prices is delivery and installation to a prepared site (flat and level) accessible by a luton delivery van. If your site has resritctions or you need your units installing at a site that is only accessible by a 4x4 this is no problem, but please contact us so we can arrange this for you.
