Choosing Which Type of Waterless Urinal

If you would prefer to talk through the choices with an experienced advisor, please call 0345 202 4535. The intention of this page is to provide a brief summary of the choices available. Further information is available via the blue links and by contacting us.

Bear in mind that...                        

• All waterless urinal designs will obviously save the same amount of water
• All waterless urinals require consumables

      (click for more about common features of waterless urinals)

• All waterless urinals need some care and attention
• No urinal is perfect, waterless or not

There is a choice between new waterless urinals and retrofitting a waterless system to existing urinals.

• For sites that already have standard urinals, conversion typically costs £60 to £100 per urinal, including labour charges.  The necessary components and instructions can be supplied for fitting by in-house personnel or an appropriate local firm. Gentworks' engineers can carry out fitting and subsequent servicing, if preferred. (click for more detail on retrofit waterless systems)

• New waterless urinal bowls vary from £124 to £450, excluding the cost of fitting.  The bowls fall into 3 main categories: (click for more detail on types of waterless urinal bowls)
  • Purpose-Built Waterless Urinals
  • Standard Urinals Bundled with a Waterless Retrofit System:
  • Modified (no spreader hole) Standard Urinals Bundled with a Waterless Retrofit System

• The total costs for converted standard urinals can exceed those for new waterless urinals. Over a long period, the consumables and maintenance requirements for converted/retrofitted waterless urinals may be greater than for some purpose-built waterless urinal bowls. However, converting existing urinals is usually more cost-efficient, and less wasteful, than installing new urinals. (click for cost comparisons for waterless urinal types)
