InBath Digital Bath and Room Thermometer
8.6/10 overallAbout £20
A floating digital thermometer that reads bath water temperature and doubles as a room thermometer.
The verdict
The Tommee Tippee InBath Digital Bath and Room Thermometer, around £20, floats in the bath to give a precise digital temperature readout and doubles as a nursery room thermometer between baths. It's a small, inexpensive purchase worth it if you'd rather trust a precise reading than estimate by elbow, though it needs an occasional battery replacement and is easy to misplace.
The NHS recommends checking bath water is comfortably warm rather than hot before bathing a baby, and a wrist or elbow test is the traditional method — but a digital thermometer removes the guesswork, especially in the early sleep-deprived weeks when your own sense of "warm enough" isn't reliable. This one floats in the bath and gives a clear digital readout, then can be lifted out and used as a nursery room thermometer between baths.
Compared with cheaper strip-style thermometers that stick to the inside of the bath, the digital version gives a more precise reading and doubles as a room thermometer, which strip thermometers can't do. The trade-off is a AAA battery to replace occasionally and a slightly higher price for what is, functionally, a simple sensor.
It's a small, inexpensive item, but one of the more genuinely reassuring purchases in the newborn bath category — precise enough to trust rather than estimate.

Frequently asked questions
Why use a digital thermometer instead of testing bath water by hand?+
A digital readout removes the guesswork of the traditional wrist or elbow test, especially in the early sleep-deprived weeks when your own sense of "warm enough" isn't reliable — it scores 8/10 for safety and support for exactly this reason.
Does the thermometer do anything besides bath water?+
Yes — it can be lifted out of the bath and used as a nursery room thermometer between baths, which cheaper strip-style bath thermometers can't do.
How easy is the thermometer to use?+
It scores 9/10 for ease of use — you just drop it in the water and read the display, and it shows an ideal bath range of around 37-38°C.
Does the thermometer need batteries?+
Yes, it needs one AAA battery, which will eventually need replacing — a minor trade-off against a strip-style thermometer that needs none, but it gives a more precise reading in return.
