Cramlington bathrooms are a regular part of my week. Full refits, shower rooms and en-suites, done by one person from strip out to the final seal.
Most of the housing here has a compact family bathroom with the original layout, and often a downstairs cloakroom. Moving a soil connection is usually the thing that decides whether a new layout is realistic, and I will tell you honestly what it costs before you fall in love with a plan.
Where mains pressure is decent, an unvented cylinder or a good thermostatic mixer gives a much better shower than a cheap electric unit, and it costs less to run.
Wet areas get boarded and tanked properly before anything goes on the wall. Almost every failed bathroom I get called to fix failed because someone skipped that step.
Every job is different, so these are guide figures rather than a quote. You always get one fixed written price after I have seen the work.
Tell me what you need and I will come and look at it. You get the price before I start.
