Average Labour Cost/Price to Fit/Install a WC/Lavatory/Toilet
To clarify the following prices it is recommended that you read the article in the INFORMATION box below the PRICES…
(These prices are based on a tradesman’s rate of £150.00 per day and a labourer if required at £100.00 per day. This includes the cost of buying and collecting any materials, dumping any waste if necessary and any incidental materials they will need. The minimum price will usually be for a half day)
How Much Does It Cost To Replace a WC/Toilet?
%[if edit]% %[endif]%
Based on our plumber’s rate of £200 per day and a labourer (if necessary) at £100 per day, plus any materials he will need. (The minimum price will usually be for a half days labour).
Were not going to get involved with the extras for tiling or new carpets etc. they are so open ended that we could be here forever and floor and wall tiling and plastering are dealt with in other sections. You have also paid for the toilet separately.
Replace an existing bathroom lavatory and cistern
The job will take one man a nice leisurely day (by the time he tips the old toilet) and he will spend £50 on tipping and materials
To undertake the above, plus adapt the soil stack including making internal plasterwork good, will take one man an extra day and a half plus £150 materials and tipping.
To fit a new toilet in a room which has never had one before, (lets say the utility room) which has a nearby external soil stack and an adjacent cold water supply. This will mean adapting the stack, fitting the toilet and making good the hole inside and out.
This will take 2 men, 1.5 days plus materials £750.00
To fit the new toilet and also fit a complete new plastic soil stack (connected to the one WC only) re connected underground and made good internally will take 2 men 2 days plus materials.
A Price Guide and Information Sheet on Changing a Toilet/WC
There’s almost a page on considerations when choosing WC’s in our bathroom section. This shorter section however will deal with the practical problems your builder/plumber will face.
Taking the old “pan and cistern” out is a simple job but the “making good” you may be looking at can be a bit nasty. This is before the new unit is fitted.
There might be a cistern shaped “hole” in the wall tiling. This will be the case if the wall was tiled after the old cistern was fitted. Unless it was tiled last Wednesday, you won’t be able to buy matching tiles any more, so that wall, or if you are really serious about it, all the tiles in the bathroom, will have to be removed and re done.
If the floor was tiled after the old “pan” was fitted, the same will apply.
Even if you are lucky and the floor and wall tiling was done before the old units were fitted, there may still be the old fixing holes exposed after the new units are fitted. I don’t care how good a grouter he is, they will always show!
The same applies to any carpet, lino, wallpaper and even plaster. There will be far more making good than you imagine.
Now, that was the easy bit! The chances are very great that the new pan’s spigot, (the small rear projection which connects it with the waste pipework) will be at the wrong height to fit into the existing 100mm (4”) diameter fixed waste pipe. This means either raising the new pan on a silly little plinth (if it’s too low) or fitting a new waste pipe, because there’s no way of lowering the pan if it’s too high unless you want to start messing with floor levels.
There are “offset” connectors which can get you out of trouble if the differences are negligible (1½ inches maximum) so let’s hope you get lucky.
If not, what is your (hopefully external) soil stack made of? If it’s plastic it can be adapted but that’s not always easy by any means. If it’s cast iron, bits can be cut out and plastic sections fitted but that’s not a job for the faint-hearted. (Have you ever tried using an angle grinder 8 foot up a ladder)?
Soil stack?…..That thick black pipe fixed to the outside wall which takes away the “night soil” and dumps it on a beach somewhere.
Night soil?…..You can only take me so far you know, I’ll say it in a minute, I will!
Now we have the water and overflow connections. Apart from aesthetics (smaller, neater etc.) modern lavatories can’t compete with the good old fashioned ones. Back in the days when we couldn’t have cared less how much precious water we used, the equivalent of Angel Falls used to be dropped from a cistern just beneath the ceiling to flush away the nasties.
Now, however, the EEC Johnnies have got their way and the cistern allows about a cupful of water out to do the same job. And quite frankly it doesn’t! So we have to flush twice and that negates the whole conservation process. My children press the little button for number 1s and the big button for number 2s – kids being kids, or nihilistic irony? Don’t ask me, I’m just a builder.
BUT the new khasis do have an integrated internal overflow and that is a good idea.
So, the plumber will very probably have to redirect the cistern’s supply pipework to a new inlet position. Make sure he does it as unobtrusively as possible and also fits an in line “isolation” valve, which makes future maintenance a lot easier. However don’t do this if the pressure is very low, because they restrict the water flow unless he gets one that is "full bore" - he'll know!
