How to install an electric shower in 2026: costs and key checks

Installing an electric shower in 2026 remains one of the most frequently requested jobs for domestic electricians. Many householders want to know what a professional typically charges, what the quoted figure usually covers, and which precautions help avoid unexpected extras-so they can plan the household budget and hire the service with greater confidence.

How much does it cost to install an electric shower in 2026?

In 2026, the average price to install a straightforward electric shower at an already-prepared connection point typically sits between R$ 120,00 and R$ 250,00 for labour only, assuming a standard job with no major alterations.

In capital cities and areas with a higher cost of living-such as São Paulo, Rio de Janeiro and Brasília-prices commonly fall between R$ 200,00 and R$ 350,00, especially for quick call-outs or visits outside normal working hours.

Where the installation requires more substantial work-such as adding a dedicated electrical point, replacing wiring, or increasing the cable cross-section-the cost can rise to R$ 300,00 to R$ 700,00, depending on complexity. For full bathroom refurbishments involving new conduit runs and changes to the consumer unit (distribution board), some electricians provide a fixed quote that may exceed this range.

Which factors influence the price of electric shower installation?

The final cost is not determined by labour alone. The property’s existing electrics, the shower unit itself, and even the type of call-out you book can all affect the total-explaining why two quotes can differ significantly for situations that look similar at first glance.

Among the main points electricians assess, the following often carry the most weight when setting both price and expected time on site:

• Condition of the existing wiring: old cables, undersized conductors, or inadequate insulation usually mean replacement is required.
• Shower power rating: models rated at 6,800 W, 7,500 W or higher demand more robust cables and protective breakers.
• Distance to the consumer unit (electrical panel): longer cable runs increase material usage (cable, conduit) and labour time.
• Need to open walls or ceilings: cutting into masonry or plasterboard generally makes the job more expensive.
• Urgency and appointment time: weekends, public holidays, or evening visits typically come with an extra charge.
• Travel: remote locations may attract a call-out or travel fee.

What is usually included in an electrician’s quote?

Not every electrician includes the same items in the price they give, so it is worth confirming whether the figure covers labour only or also includes materials and any adjustments to the existing installation. Being clear on this helps avoid misunderstandings and makes it easier to compare like-for-like quotes.

In most cases, a basic installation covers connecting the shower to the existing cables, a simple check of cable sizing and the circuit breaker, mounting the unit to the water connection point, and performing operational tests. Supplying the shower itself, buying additional cable, breakers, conduit, and any cosmetic making-good are usually priced separately-along with issuing a technical report or an ART-equivalent document, when required by insurers or building management.

How to hire an electrician and avoid surprises in the final price

Before you confirm the job, it is sensible to check the electrician’s experience, how they produce the quote, and what guarantee they provide. Nowadays, many professionals request photos and videos of the bathroom and the consumer unit so they can assess the job remotely and flag likely needs for extra materials in advance.

To minimise surprises, ask for the labour charge and an estimated materials list to be set out clearly, and agree what will count as additional work-such as opening a wall or replacing a circuit breaker. Keeping the agreement in writing (for example, via messages) and confirming the installation can safely handle the new shower’s power rating both help keep costs in line with expectations and make the arrangement more secure and transparent.
