Bathroom zone 2 (above a shower cubicle)

[DaveyH]

Which one of these diagrams is correct?

A) http://www.denmans.co.uk/images/bath_zones_2011.jpg

or

B) https://www.islandbathrooms.co.uk/image.axd?path=/content/Bathroom-Zones.jpg


On diagram A zone 2 stops level with the top of the shower cubicle.

On diagram B zone 2 extends 75cm above the shower cubicle.

They both can't be correct, can they?

Which one of these diagrams is correct?

Neither, there is no Zone associated with hand basins. AFAIC, anybody who thinks they can just invent their own rules cannot be trusted to get anything right, and everything they say should be ignored.

No, it stops 225cm above the floor.

Isn't it strange how these things come about?

Very simple diagrams in the regulations to copy and yet they make up something completely different.

Indeed - particularly since they've clearly gone to appreciable trouble to physically create those (incorrect) diagrams.

Even if there were a zone associated with sinks (has there ever been?), why on earth would anyone think it would be semi-circular? Do they really believe that it is somehow 'safer' at the edges (near the taps) than in the middle?!

why on earth would anyone think

That appears to be their philosophy.

I can remember being told and seeing diagrams at college that showed a zone 2 around the sink in a semi circular shape. Was it in the 16th ed? I don't have a regs book to hand.

Thanks. A zone around the basin would, in itself, clearly not be at all unreasonable (maybe many of us would really 'expect' it) - but, as I said, a semi-circular one as shown in those diagrams (with diameter equal to the width of the basin) seems bizarre. I wonder if the one you recall perhaps had a base to the semi-circle which was appreciably wider than the basin (i.e. extending appreciably to the sizes of the basin)?

The regs on TLC's website are 16th ed, aren'tr they? I'll have a look!

Kind Regards, John

If you go on google and search for "bathroom zones", then click images, roughly 90% of them show a zone 2 around the sink, and roughly half of them show that 75cm zone 2 above above a shower zone 1.

If you go on google and search for "bathroom zones", then click images, roughly 90% of them show a zone 2 around the sink ....

So they do! ... but many/most of the zones around basins/sinks are shown extending 600mm in all directions from the sink/basin (including to the sides), which makes a lot more sense than the ones like we are discussing here (zone only as wide as sink/basin, and semicircular). There are so many of them that I can but assume that such is what the regs once said - whether in 16th ed. or earlier.

Kind Regards, John

Even the latest Wickes catalogue has got a zone 2 around the bathroom sink/basin on page 518

There was nothing in the 16th.

 

[JohnW2]

There was nothing in the 16th.

Anyone got a copy of 15th?! ... it presumably must have originated somewhere!

2.25 from floor is outside the zone . Anything below that is in.

That's a given, but the discussion is now, where has the basin zone originated from, as it's not a real zone.

Although it does appear you're the first person to actually answer the question, in post 14!
