additional costs

Our bathroom installation cost calculator doesn't factor in everything! It gives a good overall estimate but there are some additional costs to think about for example, waste disposal! Don't forget about your old bathroom removal cost's, many old bathroom suites will go straight into a skip, your installer will charge for waste removal, be sure to check your quote for this extra. In Cornwall a 2 yard mini skip costs £175 +VAT. Bathroom layout changes will increase the overall costs quickly, with structural work to walls and ceilings adding to labour, materials and waste costs to your bathroom refurbishments. You may uncover unexpected issues, for example, when ripping out the old bathroom suite and tiles you may find corroded water pipes, outdated electrical wiring or rotten timber floor joists, all of these problems must be fixed before you can continue the renovation so unfortunanlty, they will bump up the final cost of your bathroom dramatically.
