Got the builders in

I was given some Aldi brand shortbread biscuits, they tasted revolting, I an not sure I would want to foist them on the builders, just because I found them inedible. Even the birds wouldn't eat them!

Get a couple of cheap packets from Aldi or Lidl , put in tin, put on tray with mugs. No reason why you should eat them.

Don't bake biscuits that you like - buy them the kind you don't like if you must provide biccies!
I would buy them custard creams (horrible )

The plumbers ate all my mince pies last Christmas, DH shared them out. Luckily they were bought ones.

STOP baking them goodies!! You're paying them. If you feel you absolutely have to provide comestibles for them just buy cheap biscuits. Or tell them where the nearest Greggs is!!

Lots of jobs, the bathroom is just the latest and biggest. i’ve had the roof fixed, complete rewiring, outside painting, lots of carpentry, kitchen units, ground cleared then new shed, new turf, new meters boxed in.
The new bathroom is being build by dividing a bedroom so needs walls, window and everything in it.
A month isn’t unreasonable. I may be making mince pies for workmen before everything’s done!

Promise yourself you'll go on a diet as soon as the work has finished.

Don't provide them with biscuits, Watermeadow! I keep workmen supplied with drinks but not food. Have you been quoted a fixed price for the work? If not, don't give them any reason to waste time. Our bathroom took four days too, including tiling. A month sounds far too long.

Perhaps they're spinning it out because of all the homemade biscuits!

Hmmm... my bathroom was gutted and refurbished in four days.
Perhaps the bathroom work is the tail end of other works being done ??

Put them where they are working. When I had builders in last year semi demolishing and rebuilding my conservatory I put the kettle, tea, coffee milk and bickies in the conservatory and left them to make their own. You could set up a brew station in the hall near the bathroom and they can make their own and no need for you to be interrupting them. If it's not finished after a month what the hell are they doing. A bathroom remodel shouldn't take longer than a fortnight.
