The proximity sensors in our taps and some soap dispensers use active infrared technology: they detect the infrared radiation that a close object (in their range) reflects back. This means that hands, washroom accessories or just even dirt near them will activate them.
Furthermore, infrared sensors can misinterpret certain situations and open the solenoid valve when they are not suppose to:
- Mirrors and very reflective finishes (like polished chrome) in front of them will send confusing signals if they are closer than 1.5 metre to the tap. One must be careful for example with the elements of the basin bowl: the spout of wall-mounted sensor taps should be at least 300mm away from the bottom of the sink and not facing a shiny basin plug. Tap sensors can also react if a person is wearing striking garments.
- Other infrared sensors opposite them also imply unintended triggers.
Therefore, we encourage you to read the installation guidelines the manufacturer provides and accept that accidental unlocks are a (rare) fact.

Approved Document M mentions two matters that would affect soap dispensers: contrast and location.
1) Bathroom fittings must have enough contrast among them and with the floor or walls, so that people with visual impairments or other conditions (dementia) can distinguish them.
Every surface has a LRV (light reflectance value) score. The difference between two finishes should be at least 30 points according to Document M. For example, white (85) can be combined with brushed stainless steel (45), but not with beige (70).
2) Several drawings illustrate in Document M how the toilet appliances and accessories have to be placed and at what distances. Diagram number 19 describes a unisex wheelchair-accessible toilet with a corner WC. As you can see, the soap dispenser (SD) is located above the washbasin, at 800-1000mm from the floor.
For what these regulations say about taps, we can also conclude that soap dispensers should be easily operated by all type of users.
This information has been shared following the Open Government License v3.0 of Document M.
Please, note that our interpretation could have mistakes. For further details about this, please, read the source text or consult a professional.
We've gathered in this blogpost how to calculate the expenses and which factors bear in mind when choosing a soap dispenser.
