Putting a bathroom upstairs - joists for bath

oxfordmark

Hey

We are moving a bathroom upstairs. The bath will run the same way our joists run.

I know back in the day you probably needed to reinforce joists for cast iron, but how about for modern steel baths - Do they need to be reinforced?

no but always put a lenght of timber from front to back under the feet to spread the weight

I wouldn't think so. Just a quick google tells me they weigh 45kg...that's not that much.

just as an after thought, have you had a steel bath before ?
yes they feel more solid than a cheap "plastic" one, however they have one big failing if you like a long soak, they transfer heat very well which means the bath water will go cold a lot quicker

we used to pack the space around the bath with insulation for just that reason

Isn't acrylic flimsy?

having just moved a bathroom upstairs I have all of this fresh in my mind.

you WILL need building regulations approval if you want to do things above board (so fees for this).

you will need to get the wiring signed off by building control or done by a member of a scheme (so a trained sparky).

My building control officer didnt ask for any extra joists, but my bath runs at 90 degrees to the joists (so across 6 of them) and the joists are overspecced for the size of the span, as worked out using the build reg approved loading tables.


its not the weight of the bath thats the problem, its the 150L of water + a person = 200+ kg when its full.

I would phone your local building control officer and have an informal chat with him.

Hello

I sent the relevant paperwork to my local council and made the payment a few weeks ago. We had a house rewire so everything in our new bathroom was done by a qualified electrician.

The only thing in our bathroom at the moment is a rad, extractor fan and a toilet

so you've submitted a building notice?

did you have the building control guy around to inspect the drainage runs for the toilet?

if not get him around soon and just ask him about the joists.

There are different qualities of acrylic baths. Make sure you get the thicker type. When installing, ensure that the bath is very well supported on all sides. We have never had any trouble with ours.
