Natatorium & Pool

Enjoy year round swimming at our aquatic complex

The water’s always fine at the Renaud Center Natatorium!

This state-of-the-art indoor pool facility is O’Fallon’s hub for year-round indoor water activities. With more than 10,000 square feet of exciting water features, there’s always something new to discover! This naturally-lit, colorful space is fun for all ages. Thoughtful features like zero-depth entry, dedicated lap swim times and a lazy river ensures this venue is suitable for guests of all ages and abilities.

Warm up in the mornings with aqua aerobics classes, or teach your children to love the water with our O’Fallon Swim Academy lessons. Join one of our fun pool events (like the Underwater Egg Hunt and the Pumpkin Plunge), or just enjoy a day splashing around the pool with your family. No matter what the temperature is outside, our 121,000 gallon heated pool is always comfortable year-round!

Plan a recreational trip to the pool with a Renaud Center day pass, or get full access as part of your Renaud Center membership. Secure locker rooms are available, and locks are available at the front desk.

Planning a celebration? The Renaud Center indoor pool is available to rent! Perfect for birthday parties, lock-ins and special events, a bash at the Natatorium takes all the effort out of your special day. Plus, rentals can be combined with the gymnasium and multi-purpose room for even more fun!

Natatorium FAQs

Can we bring inflatables to the pool?

Unfortunately, no. An item must be coast guard-approved to be used as a safety device. We offer free life jackets to our patrons they can use while they are swimming at our facility.

Can we bring our own food into the pool area?

No. Only water is permitted in the natatorium. We have a wet/dry concession stand that is open daily with tables and chairs a short distance from the pool.

If I am swimming laps, may I use your equipment?

Absolutely! Any of the equipment can be used by our adult patrons. We only ask that you take proper care of the items and put them away when you are finished. Please note: we do not allow children to use to swim lesson equipment.

How tall must a child be to use the slide?

Your child must be 48″ to use 185-foot water slide. They cannot wear goggles or life jackets while going down the big slide. For children under 48″, there is a kiddie slide in the zero depth area. A life jacket may be worn on the smaller slide.

What ways are there to enter the pool?

You may enter the pool four different ways:  stairs with a railing, zero-depth entry walk in, a ladder in the lap lanes or an ADA-accessible chair lift.

How deep is the pool in the natatorium?

The deepest part of our pool is 54″ or 4′ 6″. We have a zero depth walk in area and the middle of our pool is 42″ or 3′ 6″.
