Ask where the heat comes from
Mira’s comparison explains that an electric shower heats cold water as it passes through the unit, while a mixer uses hot water supplied by the home. This distinction helps frame the decision when a household wants a shower independent of stored hot water or wants to use an existing hot-water system.
It does not settle running cost, comfort or suitability by itself. Record the home’s system as confirmed by the installer, not guessed from the name of a boiler or a neighbour’s installation.
Compare the checks, not universal winners
There is no useful blanket winner for every bathroom. Compare two specific proposals against the household’s routine and the work each requires. Include what happens when other hot-water outlets are used.
A like-for-like record should cover the following questions before prices are compared.
| Question | Electric proposal | Mixer proposal |
|---|---|---|
| Water inputs | Required cold-water supply conditions | Required hot and cold supply conditions |
| Heat source | The shower’s electrical heating | The home’s hot-water arrangement |
| Professional checks | Electrical and water suitability | Water-system and product compatibility |
| Desired use | Exact head and operating controls | Exact valve and outlet combination |
| Replacement work | Existing installation assessed for the new model | Existing installation assessed for the new model |
Do not confuse category names with performance
A power shower is not simply a more powerful electric shower. Ask the supplier to identify the actual product category and requirements. Likewise, a larger overhead head does not prove a stronger or more comfortable shower.
Avoid choosing an electric replacement by a similar casing or a higher power label alone. A qualified professional must assess the requirements for that exact model. Do not alter wiring, protection, pipework or showerhead restrictions as a homeowner trial.
Create a decision that can be checked
Write the reason each option appeals: the available heat source, familiar controls, preferred spray or replacement scope. Keep that preference beside the professional’s compatibility assessment so neither gets lost.
Bring the two proposals to the showroom appointment. Use the pressure and flow guide for performance questions and the water-use tool for clearly labelled consumption scenarios, without treating either as installation approval.
The pictured supplier example is Core Barvalve Chrome. Use its exact specification when comparing options; the image does not confirm stock, showroom display availability or suitability for your room.
