A pool or hot tub in a listing is one of the more appealing features a homeowner can offer. The reality, as with most aspects of house sitting, depends almost entirely on the preparation. A pool that comes with a robot cleaner, a clear maintenance routine, and an explicit invitation to swim is a genuine perk. A pool that arrives with unclear expectations, no instructions, and a slight algae tint is a different conversation.
Caro and I have sat with pools in Linz, Austria, and Portugal. Both were outdoor, unheated, and arrived in less than perfect condition. Both were manageable. Based on those experiences and 20 sits across 12 countries with TrustedHouseSitters, this is the practical guide to pools, hot tubs, and how to handle them on a house sit.

Our Experience: Two Pools, Two Different Situations
Linz, Austria. The outdoor pool was slightly green on arrival. Not alarmingly so, but clearly not in optimal condition. The homeowner had left detailed instructions: drop two chlorine pucks into the skimmer basket every few days, run the pool robot daily, and not to worry too much about it as she would sort any remaining issues when she returned.
The maintenance was easy. Drop the pucks in, press the button on the robot, done. The pool cleared noticeably over the first few days. I swam in it. It was a great experience. An outdoor pool in a beautiful Austrian property, used properly with clear instructions and an explicit invitation to enjoy it.
Portugal. The second pool was a saltwater system, also outdoors and slightly cloudy on arrival. The homeowner had arranged for the gardener to come and add salt during the sit, so we were not required to do anything beyond basic observation. We did not end up swimming. The water was still too cold for the time of year. The maintenance expectation was essentially zero, which was reflected in the instructions.
Valencia. A third pool situation worth mentioning: the listing showed a pool in the promotional photos. We arrived for a weekend sit to find it covered and clearly not ready for use. The homeowners mentioned we could use it but in practice it was not set up. For a weekend sit it made no real difference. We spent more time playing cards and talking, which was truly enjoyable.
But arriving expecting a pool and finding one you cannot use is the house sitting equivalent of a hotel booking where the photos showed the deluxe suite and you have been placed in a standard room. Not a disaster. Potentially a disappointment. Worth asking about before you arrive.
Basic Pool Maintenance: What Sitters Are Reasonably Expected to Do
If a pool is listed as available for sitter use and the homeowner expects basic upkeep, the maintenance tasks they can reasonably ask of a sitter are:
Chlorine tablets. Dropping pucks into the skimmer basket every two to three days is a one-minute task. It is not technical, it does not require specialist knowledge, and it is clearly within the scope of basic maintenance any attentive sitter can manage. Follow the homeowner's specified frequency and quantity exactly.
Salt addition for saltwater pools. Adding a bag of salt to a saltwater pool is similarly simple. The homeowner's instructions will specify the quantity and frequency. If you are uncertain, ask before adding anything.
Running a pool robot or automatic cleaner. If the property has a pool robot, running it daily is a minor task that takes seconds to initiate and maintains the pool floor and walls without effort from the sitter.
Skimming the surface. A skimmer net on the edge of the pool takes thirty seconds to remove floating debris before it sinks and adds to the cleaning burden. If the pool is in regular use, a quick skim every day or two keeps the surface clean with minimal effort.
Reporting. If you notice the pool changing colour, the water becoming cloudy, or any equipment appearing to malfunction, photograph it and message the homeowner promptly. Early communication prevents small issues from becoming larger ones. Our documentation habit applies here as much as anywhere else on a sit.
What Is Not a Sitter's Responsibility
The boundary matters. Basic upkeep following clear instructions is reasonable. Specialist pool chemistry, equipment repair, and anything requiring professional knowledge is not.
Chemical testing and balancing. Testing pH, alkalinity, and other chemical parameters requires knowledge, proper test equipment, and an understanding of how to adjust readings. If the homeowner expects a sitter to manage full chemical maintenance, this should be stated explicitly before the sit and must be something you are comfortable with. It is not a default expectation. If the water chemistry deteriorates during a sit despite following instructions, that is not the sitter's fault.
Equipment repairs. A pump failure, a heater breakdown, a leak, or any mechanical issue with pool or hot tub equipment is the homeowner's responsibility. Contact the homeowner immediately when something malfunctions, document what you observe with photographs, and let them arrange the repair. You are not a pool technician and should not be expected to diagnose or fix equipment problems. The costs belong to the homeowner. A sitter should never be in a position where they have paid for pool repairs and are waiting to be reimbursed. Our house sitting legal issues guide covers what happens when unexpected costs arise during a sit.
Algae treatment beyond basic prevention. If a pool arrives with significant algae growth requiring shock treatment or specialist chemicals, this is a maintenance backlog the homeowner is responsible for addressing before the sit or arranging a professional to handle during it. Adding a few extra chlorine pucks to a slightly green pool following the homeowner's instructions is reasonable. Managing a serious algae problem with no guidance is not.
Hot Tubs: The Same Principles, Different Chemistry
We have not personally managed a hot tub on a house sit, but the same framework applies with some additional considerations.
Hot tubs require more frequent chemical management than pools. The smaller volume of water combined with higher temperatures and heavy use creates conditions where bacteria can multiply quickly. The standard maintenance routine for a hot tub in regular use involves checking and adjusting pH and sanitiser levels several times per week, rinsing the filters periodically, and shocking the water after heavy use.
If a hot tub is included in a listing and the homeowner expects it to be maintained, the welcome guide should include a specific, step-by-step routine with product names, quantities, and frequencies. A general "add chemicals as needed" instruction is not adequate for a hot tub. If the instructions are unclear, ask for clarification before the sit. Not after the water has become an issue.
The same repair boundary applies: any mechanical failure with a hot tub heater, pump, or cover belongs to the homeowner.
The Covered Pool Problem: What Listing Photos Should Show
The Valencia situation raises a broader point about how pools and hot tubs are presented in listings.
A homeowner who photographs their pool for the listing is implicitly advertising it as a feature of the property. If the pool will not be available for use during the sit. Whether because it is covered for winter, undergoing maintenance, requires a level of chemical attention that is not reasonable, or simply needs more work than the homeowner has had time to invest. This should be stated clearly in the listing and confirmed at the pre-sit video call.
Showing a pool in listing photographs and then disclosing at handover that it is covered and not usable is the same category of misrepresentation as overstating any other feature of the property. Our homeowner misrepresentation guide covers how to handle situations where the reality does not match the listing. For a pool specifically, the practical questions to ask before confirming any sit are:
Is the pool available for sitter use during the sit dates? Is it currently maintained and swimmable? What maintenance is expected of the sitter, and how long does it take per day? Is there a contractor or service person who will be coming to the property for pool maintenance during the sit? Is the pool heated, and if so will it be running during the sit?
These questions take thirty seconds in a video call and remove all the uncertainty that the Valencia situation created.
What the Welcome Guide Should Include for Any Pool or Hot Tub
If you have a pool or hot tub and are listing your property on TrustedHouseSitters or any other platform, the welcome guide should include:
The current condition of the pool or hot tub and whether it is ready for use. The exact maintenance routine. Product names, quantities, frequencies, and which day of the week or how many days apart. Where the products are stored. How to operate the robot or automatic cleaner, if there is one. The location of the circuit breaker and pump controls, and what to do if a fault indicator appears. The name and contact number of the pool service contractor, if one is used. Explicit confirmation that the sitter is welcome to use it. Or equally clearly, if they are not.
A welcome guide that covers these points sets both parties up well. A sitter who is given a clear routine and an invitation to enjoy the pool will maintain it more attentively than one who is uncertain about what they are supposed to do. Our cleaning and etiquette guide covers the broader approach to property maintenance during different sit lengths.
Using the Pool or Hot Tub as a Sitter
If you have been invited to use the pool or hot tub, use it. This is one of the genuine privileges of house sitting. Access to amenities that would otherwise be significant luxuries. Swimming in an Austrian outdoor pool, soaking in a hot tub in a French farmhouse, using a heated lap pool in a central London property. These are experiences that belong to a lifestyle, not a holiday, and they are part of what makes house sitting one of the most rewarding ways to travel.
A few points of common sense worth keeping in mind. Keep the area clean. Treat the pool deck, sun loungers, and towel storage with the same care as any other part of the home. Follow any specific rules in the welcome guide about times of use, particularly if neighbours are close. Shower before entering the pool if the homeowner has a system that relies on specific chemical balance. And if friends or guests are not mentioned in the listing, confirm with the homeowner before inviting anyone to use the pool. It is their property and their utility bills. Our what house sitters can and cannot change guide covers the broader principle.

Frequently Asked Questions
Am I expected to maintain a pool during a house sit?
Only if the welcome guide or pre-sit conversation explicitly says so. Basic tasks like dropping chlorine pucks in a skimmer or running a pool robot are reasonable to expect if clearly instructed. Full chemical management, testing, or equipment repair are not default sitter responsibilities. If pool maintenance was not mentioned in the listing or welcome guide and becomes a significant time commitment, you are within your rights to push back.
What do I do if pool equipment breaks during a house sit?
Photograph the issue, contact the homeowner immediately, and do not attempt repairs yourself. Pool and hot tub equipment repair is specialist work and the cost belongs to the homeowner. Document what happened and when, let the homeowner arrange the solution, and do not pay for repairs out of pocket.
Can I use the pool or hot tub during a house sit?
Yes, if the homeowner has explicitly invited you to. Most homeowners who mention a pool in their listing are happy for sitters to use it. Confirm this in the pre-sit video call if it is not stated clearly. Do not invite guests to use the pool without the homeowner's permission.
What if the pool in the listing photos is covered when I arrive?
This is a legitimate concern to raise. A pool shown in listing photographs and then disclosed as unavailable at handover is a form of misrepresentation. Confirm whether the pool will be usable during your specific sit dates at the pre-sit video call. If it is not available, you may want to factor that into whether the sit is still the right fit.
