A small bathroom renovation in Dublin typically takes 5 to 10 working days from the first day of demolition to final sign-off. That figure covers a full strip-out and refit, including new tiling, sanitary ware, shower, flooring, and fixtures, in a bathroom of 3 to 5 square metres. More complex jobs involving layout changes, structural alterations, or specialist finishes can extend the timeline to 3 to 4 weeks.
What affects how long a bathroom renovation takes?
The single biggest variable is scope. A cosmetic refresh, such as replacing a shower tray, retiling a splashback, or fitting a new vanity unit, can be completed in 2 to 3 days. A full gut-and-refit that moves the soil pipe, relocates the shower, or requires replastering will take considerably longer. After 16 years renovating bathrooms across Dublin, the jobs that run over schedule almost always do so for one of three reasons: delayed materials, concealed issues behind existing tiles, or underestimating the drying time for wet trades.

Stages are sequential. Drying times shown are minimums — Irish climate conditions may require longer.
How long does each stage of a bathroom renovation take?
Each trade has its own pace, and the stages are sequential. You cannot tile until the waterproofing is dry, and you cannot fit sanitary ware until tiling is complete. Rushing any stage creates problems that are expensive to fix later.
Strip-out and preparation: 0.5 to 1 day
Removing existing tiles, sanitary ware, and flooring. Older Dublin properties, particularly Victorian and Edwardian terraces in areas like Rathmines, Ranelagh, and Drumcondra, often have multiple layers of tiles and screeds built up over decades. This can add half a day to the strip-out.
First fix plumbing and electrical: 1 to 2 days
Pipework repositioning, waste runs, and any electrical first fix, including underfloor heating and extractor fan wiring. If drainage needs to be re-routed, this stage takes longer and may require building control notification under the Building Regulations (Part H).
Plastering and waterproofing: 1 to 2 days, plus drying time
This is where timelines are most commonly underestimated. Plaster must cure before waterproof membrane is applied, and membrane must dry before tiling begins. In Irish weather conditions, particularly in winter or in bathrooms with poor ventilation, drying times can be 24 to 48 hours per coat. Cutting corners here is the primary cause of future damp and tile failure.
Tiling: 1 to 3 days
The duration depends on tile format, pattern complexity, and the number of cuts required around obstacles. Large-format tiles (600x600mm and above, which are common in modern Dublin bathroom renovations) require more precise substrate preparation and slower installation. According to the Tile Association, floors tiled with large-format porcelain need a minimum 24-hour cure before foot traffic.
Second fix plumbing and electrical: 0.5 to 1 day
Fitting the toilet, basin, shower unit, radiator or towel rail, and all electrical finishes. This stage moves quickly when first fix has been done correctly.
Snagging and final sign-off: 0.5 days
A proper snagging walkthrough catches grout inconsistencies, silicon finish quality, alignment issues, and any items requiring adjustment. Do not skip this stage. It is the difference between a renovation that looks good on day one and one that still looks good in five years.
What causes bathroom renovations to run over schedule?

Delays are rarely the fault of the main contractor alone. The most common causes, in order of frequency, are:
- Materials out of stock or on long lead times. Popular tile ranges and sanitary ware from European suppliers can have 4 to 8 week lead times. Ordering materials before work begins is standard practice on any well-managed job. Always confirm availability before signing off a specification.
- Concealed problems discovered during strip-out. Wet rot, corroded pipework, substandard original construction, and asbestos-containing materials in older properties (pre-1999 builds) are not visible until walls and floors come out. A contingency of 10 to 15% on both budget and timeline is prudent for any Irish property built before 1980.
- Inadequate drying time for wet trades. Waterproofing and adhesive manufacturers publish minimum drying times for a reason. In a humid Irish climate, those times should be treated as minimums, not targets.
- Scope creep. A small bathroom renovation that begins as a retile often expands once walls are open, such as replacing a bath with a walk-in shower, adding underfloor heating, or relocating the toilet. Any change to scope after work has started adds time and cost.
Does the size of the bathroom affect the timeline?
Yes, but less than most homeowners expect. The overhead trades, including plumbing, electrical, and waterproofing, take broadly the same time regardless of whether the bathroom is 3 or 6 square metres. The variable that scales with size is tiling and screed. A good tiler can typically lay 8 to 12 square metres of standard wall tile per day, and 6 to 8 square metres of floor tile per day. In a typical Dublin apartment bathroom of 4 square metres, tiling is rarely the bottleneck.
How long does a bathroom renovation take in a Dublin apartment?
Apartment bathroom renovations in Dublin come with two additional constraints that can affect the timeline. First, building management companies often restrict working hours, typically to 8am-6pm Monday to Friday, with no weekend working. Second, material access through shared corridors and lifts requires careful planning to avoid delays on delivery days. In our experience across apartment buildings in Ballsbridge, Clontarf, and Ranelagh, allow an extra day on the standard timeline to account for these logistics.
Can I use my bathroom during the renovation?
No. Once strip-out begins, the bathroom is non-functional until second fix is complete. For a 5 to 10 day renovation, you will need access to another bathroom in the property or make alternative arrangements. If you have only one bathroom, discuss this directly with your contractor before work starts. A well-organised team will sequence the work to minimise the period when the room is completely out of use.
What questions should I ask a contractor before booking?
Before committing to a contractor for a bathroom renovation in Dublin, ask these directly:
- How many bathroom renovations have you completed in the past 12 months?
- Who will be on site each day, your own team or subcontractors?
- What is your process for handling concealed problems discovered during strip-out?
- Will you provide a detailed, itemised quote rather than a lump sum?
- How do you handle drying times for waterproofing and adhesives?
- Are you registered with the Construction Industry Federation (CIF)?
A contractor who cannot answer these questions confidently is not the right choice for your bathroom.
