We are currently smack in the middle of bathroom renovations. The 'main bath' off the hallway (the one the kids used for years) was done first, and now they are working on the master bath. Both rooms were original builder grade materials, almost 21 years old.
For the main bath we didn't move any plumbing or electric. Gut all fixtures (shower/tub, toilet, vanity, floor) to the studs. New tub, new tile surround (to the ceiling), new tile floor, new vanity and granite top with undermount sink. Semi-frameless shower doors as well. We had to pay separately for vanity, granite, tile and shower doors. The contractor logically explained that these are considered 'personal choice' items and its far easier for him to estimate his costs for demo and labor than to provide allowances for fixtures. I was asked to choose Moen faucets/shower fixtures as that was his preferred valve control. Included in his price was anything in chrome; other finishes would have an upcharge. His contract price for this space was $8800 and all in we spent $12,000. We are absolutely thrilled with the results.
Our master is a different story. This remodel includes electric and plumbing changes as we removed the big soaking tub (aka dust receptacle) and reworking that space into a MUCH bigger shower...overall about 24-25 square feet. All the plumbing for the tub had to be moved and re-worked for the shower, and the old shower lines cut and capped. We are going from one light fixture over the double vanity to two fixtures since we're getting a 'tower cabinet' in between the two sinks. In addition, there is a 2ftx5ft window that will end up in the shower; that window is being replaced with a custom acrylic glass block privacy window designed for a wet location. All new tile, fixed shower head plus a hand-held on a slide bar, new overhead lighting above the shower (recessed LEDs) that will be on a dimmer switch. Once again, we are responsible for tile, vanity and granite costs. Frameless shower glass will be installed but I have a $1000 allowance for that and shouldn't go over. Contractor bid $25k, all in we expect to hit $30k.
For both bathrooms, contractor price included new toilets. For the main bath, it included the new tub as well. All material disposal costs are included (matter of fact, there's a dumpster parked in my driveway right now).
There may be some who think the price is excessive. I can tell you that for me, its worth every penny. My builder is amazing...he is on top of every detail and keeps me informed every step of the way. He deals with his own sub-contractors who are amazing, he handles all the permit and inspection details. He's earned our trust and now carries a key to our house so we can go about our day at work without interruption. He texts or calls me at the end of each day to update the progress and give me the plan for the next day. Dropcloths are every where while they work, and at the end of the day the carpets on the stairs and second floor are vacuumed...every day. They sweep the garage and driveway every day.
,) now I have an idea of how much I'll need to save to bring our bathrooms up to standard. Bottom line= lots
