Tanking price - Tile Advice

[Ian]

£20 per m2 usually gives a decent bit of profit, usually works out anywhere between £100-150 for a shower.

I need to double my price then Do you tell customers what the option is for tanking and cost it as a recommended option?

I just priced a job today & told them that the shower needs waterproofing.
I'm doing a new build starting tomorrow & ive recommended that the upstairs ensuite shower gets a tanking kit but not sure whether the builder wants to pay the extra or not.

 

[Old Mod]

Yep £150 for me too, for full shower.
£100 round a bath.

 

[Flintstone]

A tanking kit costs about £50 for paste and tape.

I don't price it separately. It's listed in the quote. Discussed beforehand that it'll be included and explained why. If they don't want it, they don't get me.
I normally use kerdi or ardex wpc if i don't get to build the walls. I will build in a days labour to prep an area (ok, it might just be 2 to 3 hours though!) and materials + 40% so anywhere from 200 pounds upwards built onto the price.

Tanked a new build shower today, amazed that the builder listened to me.
I reckon it took me 4hrs by the time I cut the tapes & put 2 coats of paste on the walls (3 sided shower 900x760)
£80 for the 4hrs work & £50 for the paste roughly so not far away at £150- £200 for the completed job.

I told the plumber to ditch the classi seal as I was tanking it.
Mapegum with Mapei tape.

Out of interest have you called Mapei technical support to ask if this would invalidate the guarantee they offer? Would be interested to find out.

By using two different manufacturers I cant imagine they'd guarantee it at all, but to me it's a no brainer, how can it go wrong

 

[LM]

I prfer to use a self adhesive tape in this system as well

If it's fitted correct then it would be ok but I find the plumbers leave too much silicone on the top edge & leaves you with a lip at the bottom of the tile.
