For protection of stained wood i always went with polyreuthane. Is varnish better?

If those prices don't include the electrician's costs of connection then to me they don't match up and I'd say your supplier/installer can't do maths lol. Pricing will change between supplier and of course electricians, and of course I'm working off the impression that the floors are flat where you want it installed. If the quote includes the electrical work, as in it covers everything besides tiling to where you can switch it on, then it looks reasonable to me and sits around the ballpark of what we paid. With the electrician's connection costs included then the figures match up better between the bathrooms and the living area, looking at it from a total per m2 viewpoint. If it includes the floor covering as well, then I'd say get on the phone and book the job straight away before they realise their mistake lmao. For instance if the quote is just for material and install, without electrical connection then the two bathrooms are quoted at $166.66 per m2 and the living area is quoted at $53.57 per m2. A large difference at cost per m2. If however the quotes include the electrical connection then you can average out the m2 cost across all three rooms and it amounts to $73.53 per m2. The electrician would be charging the same price for connection of each room (with only minor differences) if there is nothing out of the ordinary in any room. That means it's a static cost in each room that could make the bathroom quotes look inflated, and the living room look on the cheaper side. When you have a m2 quote on something across multiple rooms of different sizes, it's important to factor in anything outside of materials that's included in the quote. Assuming the install could be considered standard (whether it be underfloor heating, tiling, carpet, etc.) there will be other costs involved such as labour hours, wiring connection, installation materials, etc. Some can be considered static such as the electrician installing a single thermostat in each room, whatever actual size that room may be. Others will be more fluid such as labour hours for the tradesmen doing the install - will take a lot longer to lay tiles in a room of 56m2 than it will to lay them in a room 6m2. Whenever you are given a quote involving installations by m2, it's important to get them to detail what exactly is included in the quote. If you don't do this you run the chance of ripping yourself off. Let's say you get 3 different quotes from underfloor heating suppliers who all give you different prices but without details. One may look more expensive than the other two but actually be cheaper overall due to including everything up to 'turn on' phase, where the other two may only include supplying and laying the underfloor heating with you having to organise your own electrician after install.

yes oklouise, I hear all that - absolutely yes it's all about clients understanding/working out properly what they need.........and it's great to be able to seek comments/thoughts on Houzz from a broad range of backgrounds/experiences......the issue though is when it gets into territory where (from my perspective) clearly experience and professional skill will help resolve the problem most effectively (such as on this particular one) that it's therefore appropriate to suggest this the advised way to go.......I suppose I see frequently here capacity for designers to be able to "cut to the chase" most effectively, but of course this needs to be done in a manner underpinned by a thorough understanding and establishment of what the client needs in context, and yes very often the client will require more time to work this all through.........I however still see our role as relevant in that part of the process though, and not necessarily having to "wait" for that to happen, because ultimately as professionals in this position (i believe) have a responsibility (as part of our role as a consultant) to educate people appropriately and thoroughly so they can develop the skills to be able to consolidate their decision-making most appropriately for themselves and the project - by the end of the journey, I find my clients are rather quite the experts!..........this however involves a collaborative approach, egos are shelved and an intimate working relationship, which is very different from the approach (that some designers work to) which is essentially selling a "product" or particular end result, rather than a service....significant difference, and again, horses for courses ;)
