Cost of swapping a bathtub for a shower in Cádiz

Replacing a bath with a shower tray in Cádiz costs between €1,900 and €3,500 fully fitted, depending on the type of tray, the shower screen, and whether the tiling covers the whole area or only the essentials. It is the standout renovation in homes right across the province, from flats in the old quarter of El Pópulo to semi-detached houses in Chiclana or San Fernando, because it improves accessibility, gains space, and leaves the bathroom looking brand new without having to overhaul the entire room.

In this guide we walk you through the real breakdown of what this work costs in 2026, which line items appear in a fixed-price quote, what options suit your type of property, and how to plan the job so it takes as little time as possible. All prices are based on current market rates across Cádiz, San Fernando, El Puerto de Santa María, Puerto Real, Chiclana, and Jerez.

What does replacing a bath with a shower in Cádiz actually include?

A fully fitted bath-to-shower conversion covers every line item so you do not have to coordinate anything yourself. From removing the old bath through to the final finish with screen and taps, everything is wrapped into a single fixed quote. These are the standard items included by Reformas By Bianca:

• Removal of the existing bath and waste disposal, skip hire included at no extra charge.
• Floor preparation: levelling the base and fitting a new waste outlet suited to the chosen tray.
• Supply and installation of the shower tray, resin, ceramic, or wet-room, according to your preference.
• Tiling of the affected area, half-wall or full wall, with tiles chosen by you.
• New taps: single-lever mixer or thermostatic bar, with hose and handset included.
• Glass shower screen (fixed panel, sliding, or hinged) including all framework.
• Full plumbing adaptation: hot and cold feeds, isolating valve, and waste connection.
• Final clean-up of the work area and removal of all surplus materials.

The result is a bathroom ready to use from the first day after the work is finished, with no need to hire anyone else or source materials separately. All management, materials, and labour appear on a single invoice.

Cost of replacing a bath with a shower by tray type

The type of shower tray is the single biggest factor in the final price, not only because of the cost of the tray itself, but because each option involves a different level of work. Below is a table showing the real price ranges we work with across Cádiz and the surrounding area in 2026:

The resin tray is the most popular choice in flats across Cádiz city and San Fernando: it is lightweight (between 15 and 25 kg, compared with 50–70 kg for a ceramic tray), comes with anti-slip as standard, and is available in more than 30 colours and textures. Installation is also faster because there is no curing time, which cuts the job by roughly half a day.

A ceramic or ultra-slim tray holds up better against scratches and everyday wear. It is a good choice if you have young children or pets. The slightly higher price is mainly down to the extra weight, which requires a more thoroughly prepared base, and the more precise alignment of the waste outlet.

A wet-room floor (a continuous gradient surface draining to a central gulley) gives the most premium and visually clean result: no raised edges, no tray frame. However, it requires considerably more labour, the gradient must be formed in mortar, the surface waterproofed with bituminous membrane or PVC sheet, and drying times observed, which explains both the higher price and the slightly longer programme.

Factors that can push the cost of a bath-to-shower conversion higher

The base price covers a standard conversion, but there are common extras worth knowing about before you compare quotes. These are the ones that most affect the final figure:

• Bespoke screen or frameless fixed glass panel: between €200 and €600 more than a standard sliding screen. The cleanest aesthetic option, but it requires precise measurement and specific fixings.
• Full tiling of all three walls in the shower area: compared with tiling only the essential surfaces (one wall and part of a second), covering all three walls adds between €300 and €500 in materials and labour, though the visual result is worth it in most cases.
• Rerouting the waste: if the new tray has different dimensions to the bath, or is repositioned within the room, the waste pipe must be redirected. This adds between €200 and €400 depending on the distance and accessibility of the stack.
• High-end thermostatic bar: between €150 and €300 more than a standard single-lever mixer. Maintains a constant temperature and prevents scalding, strongly recommended where children or elderly people are living in the home.
• Updating the WC or vanity unit at the same time: if the sanitaryware is more than 15 years old, doing it all in one visit saves 20–30% on labour compared with scheduling a separate job.
• Recessed LED lighting in the shower area: between €80 and €200, depending on the number of fittings and whether a new electrical circuit is needed.

Tip: if the work is already open, it pays to update anything that is looking tired, taps, vanity unit, mirror. Doing everything in one go reduces the total labour cost by 20 to 30% compared with coming back a second time.

Replacing a bath with a shower in older flats in Cádiz: what you need to know

Cádiz has one of the oldest housing stocks in Andalusia. In neighbourhoods such as El Pópulo, La Viña, Santa María, and the Barrio de la Palma, buildings of more than 40 years old are common, with narrow bathrooms, cast-iron pipework, and asbestos-cement stacks. Converting a bath to a shower is not only perfectly feasible in these flats, it is one of the most frequently requested and most appreciated renovations.

The key is to check the condition of the waste stack and the existing plumbing before drawing up a quote. During the preliminary visit we verify the waste pipe diameter (it must be at least 50 mm for a shower tray, compared with the 40 mm typically found on older baths), the pipe material, and whether there is any moisture in the floor slab. If a section of stack needs replacing or the iron pipes need to be swapped for multi-layer pipe, we include that in the quote so there are no surprises.

In properties in Extramuros, Bahía Blanca, or the newer parts of Cádiz city, as well as in San Fernando, El Puerto de Santa María, Puerto Real, and Chiclana, flats tend to date from the 1980s to 2000s with more modern installations. In these cases the conversion is more straightforward: the plumbing is generally in good shape and the waste outlet is already the right diameter, which simplifies the job and often brings the price towards the lower end of the range.

Shower screen comparison: types and prices in 2026

The shower screen is the second most significant item in the budget after the tray. Choosing the right one affects both the price and the day-to-day usability of the bathroom. These are the most common types we install:

In flats within the historic centre of Cádiz, where bathrooms often have irregular shapes and high ceilings, a bespoke screen is sometimes the only viable option. In more recently built homes in San Fernando, Chiclana, or Jerez, a standard sliding or fixed panel fits without difficulty and keeps the budget in check.

Accessibility and adapted bathrooms: regulations and grants in Cádiz

One of the main reasons people replace a bath with a shower is to improve accessibility, particularly in homes where elderly or reduced-mobility residents live. An ultra-slim or flush-to-floor shower tray removes the step of the bath surround (which can stand more than 50 cm high) and significantly reduces the risk of falls.

For a bathroom to meet current accessibility standards under the Spanish Technical Building Code (CTE DB-SUA), the tray must have a Class 2 or higher anti-slip surface, the entrance must be clear of any lip taller than 2 cm, and there must be enough room for a turning circle of 120 cm in diameter, or at minimum enough space for the user to enter and move safely. In smaller bathrooms, such as those found in many flats in La Viña or El Pópulo, space can be optimised with a bespoke tray and a hinged screen or a simple curtain instead of a rigid screen.

In addition, the Junta de Andalucía and several local councils across the province of Cádiz periodically offer grants for the removal of architectural barriers in residential properties. These subsidies can cover between 40 and 75% of the cost of the renovation where the applicant is over 65 or holds a recognised disability status. We recommend checking the current funding round when planning the work; we can point you in the right direction regarding the documentation required.

If you need an adapted bathroom for an elderly person or someone with reduced mobility, we can include grab rails, a fold-down shower seat, and a thermostatic bar as standard.

How long does it take to replace a bath with a shower in Cádiz?

A standard bath-to-shower conversion using a resin or ceramic tray takes 2 to 3 working days. If all three walls are tiled or a wet-room floor is chosen, the programme extends to 4–5 days to allow for mortar curing, waterproofing, and grout drying times.

Here is the typical breakdown for a 3-day job:

• Day 1: Removal of the bath, breaking out the affected tiles, preparing the floor, and fitting the new waste outlet. The shower tray is set in place by the end of the day.
• Day 2: Tiling the shower area, fitting the taps and making the plumbing connections. Grout is left to cure overnight.
• Day 3: Fitting the shower screen, silicone sealing, water-tightness test, and final clean. The bathroom is ready to use that same afternoon.

During the work only the shower area is out of action. If you have a second bathroom in the property you can use it as normal throughout. If it is the only bathroom, we plan the schedule so that by the end of the first day the tray is already in place and you can shower provisionally if needed.

How to choose the right shower option for your bathroom in Cádiz

The best option depends on three factors: the size of your bathroom, your budget, and how it will be used. To help you decide, here is the guidance we give our clients during the site visit:

• Small bathroom (under 4 m²), tight budget: standard resin tray + sliding screen. The most space-efficient and cost-effective combination. Guide price: €1,900–€2,300.
• Mid-sized bathroom (4–6 m²), mid-range budget: ultra-slim resin or ceramic tray + fixed glass panel. A good balance of aesthetics and practicality. Guide price: €2,300–€2,800.
• Large bathroom (over 6 m²), higher budget: wet-room floor + fixed panel or open shower. The most premium finish. Guide price: €2,500–€3,500.
• Adapted bathroom for elderly or reduced-mobility users: flush-to-floor tray + hinged screen or open shower + grab rails + thermostatic bar. Guide price: €2,500–€3,500.

Do you need planning permission to replace a bath with a shower in Cádiz?

In the vast majority of cases, no. Replacing a bath with a shower is classified as a minor internal refurbishment that does not affect the structure or the external facade of the building, so no building licence is required from Cádiz City Council or from most other local authorities in the province, including San Fernando, Chiclana, El Puerto, Puerto Real, and Jerez. A responsible declaration (declaración responsable) submitted online is all that is needed, and confirmation is immediate.

The exception applies to protected buildings in the historic centre (listed as BIC or on the local heritage register), where any intervention (even an internal one) may require a preliminary report from the Culture Delegation. If your property is in El Pópulo, Santa María, or another listed building in La Viña, we check this before starting and advise you of any additional steps required. Reformas By Bianca handles the responsible declaration on your behalf at no extra charge.
