Building a gunite pool is a massive investment, and understanding how long it takes to fill one is critical to planning your project timeline. Whether you’re considering adding a pool or already have one under construction, knowing the details will help you prepare for the next steps. So, how long does it take to fill a pool with gunite, and what factors come into play? Let’s dive into the process.

Understanding Gunite Pool Basics

Gunite is a durable and customizable mixture of concrete and sand applied using a high-pressure hose. Due to its flexibility in design and long-lasting strength, it’s a popular choice for gunite pool installation in Missouri. Once the gunite shell is applied and cured, it forms the base of your pool.

But before filling it with water, the gunite needs adequate time to cure. Typically, this takes around 28 days. During this time, the material hardens, making the pool ready to be filled.

The Role of Pool Size and Shape

The size and shape of your gunite pool are significant factors in how long it takes to fill. Larger pools will naturally require more water and take longer to fill. A standard backyard pool, which holds between 15,000 and 30,000 gallons, may take between 24 and 48 hours to fill.

The filling process for custom-shaped pools or larger installations often found in luxury homes could take longer than 48 hours. In contrast, a small plunge pool might be ready in under a day.

Water Pressure and Fill Rate

Another crucial factor is your home’s water pressure. The Rate at which water flows into your pool will determine how long it takes to fill. On average, water fills a pool at about 12 gallons per minute when connected to a garden hose with standard household pressure.

If you have lower water pressure, it will slow the process, while homes with high pressure can speed things up. You can measure your home’s water pressure to estimate more precisely how long pool filling will take. For instance, in Missouri, certain municipalities may have varying water pressure levels, which could affect the timeframe for your gunite pool installation.

Weather Considerations in Missouri

Missouri’s weather also affects the pool-filling process. If you’re filling a pool during the summer months, evaporation can delay the process, requiring you to add more water over time. Additionally, heavy rains during the spring and fall can affect the curing process and the timing of filling the pool.

Choosing the right time to fill your pool is crucial. Waiting for dry, stable weather conditions will help avoid unnecessary delays.

Alternative Water Sources: Should You Use a Water Truck?

Using a water truck service is an option if time is a concern. Depending on the size, this service delivers water directly to your location and can fill a pool within a few hours. Although it’s more expensive than using your home’s water supply, it might be worth considering for larger pools or saving time.

In Missouri, local water delivery services are available, and many gunite pool owners choose this method to get their pools ready faster. However, be sure to weigh the cost against the convenience.

Final Inspection Before Filling

Before filling your pool, ensure all equipment is in place, including the pump, filter, and plumbing system. A final inspection guarantees no issues that could interfere with the water-filling process. If you complete this step, you may avoid complications, like leaks, that could delay your pool’s readiness.

Once your pool is inspected and ready, filling it becomes the final puzzle piece. This step ensures peace of mind as you prepare to enjoy your new pool.

A gunite pool installation in Missouri takes a lot of work, but understanding the factors that affect the process can help you better manage your expectations. From the size and shape of the pool to your local water pressure and weather, each element influences how long it takes. On average, it will take about 24-48 hours to fill a standard pool, but larger or more complex designs may take longer. With proper planning and consideration of alternative water sources, you can streamline the process and start enjoying your pool as soon as possible.

Frequently Asked Questions

1. How long does gunite fully cure before pool construction can continue?

Gunite typically takes about 28 days to cure fully, but other construction processes, like tiling and decking, can often continue before this period ends. It’s essential to allow proper curing for the pool’s long-term durability.

2. Can I swim in the pool immediately after filling it? 

No, after filling your pool, you need to balance the water’s chemicals, which can take a few days. Testing the water’s pH, chlorine, and alkalinity levels ensures it’s safe to swim.

3. What maintenance is required for a gunite pool over time?  

Regular maintenance includes balancing water chemistry, brushing the pool walls to prevent algae, checking the filtration system, and resurfacing the pool every 7-10 years to maintain its structure and appearance.

4. What are the common problems with gunite pools?

Over time, gunite pools can develop cracks due to ground movement or improper maintenance. Resurfacing and patching can help, but regular upkeep, like maintaining chemical balance, reduces these risks.
