hi all,

i wanna ask for opinions regarding a small toilet renovation - whether price reasonable or not. my parents got quoted almost 9k for it. i don't know whether i should list out all, but here are the major ones:

install new piping work c/w floor outlet pipe - 950
supply & install new floor pipe line at toilet c/w install of toilet bowl - 1250
supply & install plaster ceiling & cones (4' x 7') - 450
supply & install wall tiling (152 sq ft) - 1450
supply & install floor tiling (4' x 7') - 336
shower screen 4' x 6' - 980
supply & install new piping work and install water heater c/w wiring work - 860
painting - 360

honestly i can't really figure out how this works. i asked abt buying own supplies n look around for toilet bowl price n all n told my mum abt it to cut cost as much as possible, but the contractor said if we buy our own they wont be responsible afterwards if anything happens for things like water heater etc. my parents still want to do renovation for other part of the house, so if this price is reasonable i guess we could proceed with this contractor. is this quotation reasonable?

thank you in advance.
