We've brought shower sink taps toilets etc all from different shops
No one shop sold every thing we wanted at the right price
We saved a lot of money!
For example tiles were £25 sm in one shop online £10 -
B&Q bath screen etc was £600 v the £190 we paid
With labour and plumbing electrics and floor etc - total cost £3000
But - we've managed better quality fitting the 'standard' fittings supplied by the main companies
