Where is the house? What kind of weather are you having? How long has this been going on? What is the foundation? Where in relation to outside walls is the bathroom? Which wall of the bathroom is the faucet?
Water is always warmer here in summer because reservoirs, treatment and storage tanks, ground and pipes in it are warmer. Slab foundations are warmer especially near perimeter. Slab can then warm water, conversely slab directly over warm supply line can be warmer. Pipes in exterior walls, such as at bath tub are warmer. Pipes in crawl space are warmer. This can all happen gradually as weather warms, especially slab warming. You might not really notice it, then one day you do.
Winter time the opposite happens, cold floor, hot water not hot enough.
Measure twice, cut once.
Look at the nail, not the hammer. Watch the fence, not the blade.
If you hook your thumb over your belt you won't hit it with the hammer or leave it layin on the saw table.
