Understanding the landscape of above-ground pools is crucial before making a purchase.

Throughout this In The Swim Oasis pool review, we will weigh the pros and cons, scrutinize the build quality, and help you decide if this is the right investment for your home and family.
The In The Swim Oasis 18 ft Round Above Ground Swimming Pool is not your standard all-in-one starter kit. It is specifically engineered as a replacement pool structure for homeowners who already own a functioning pump, filter system, and ladder. This is a crucial distinction in the market. Many competitors bundle these items, increasing the upfront cost, but the Oasis allows you to reuse your existing equipment, potentially saving you hundreds of dollars. In this In The Swim Oasis pool review and rating, we will focus on the core structure: the 52-inch steel pool wall, the durable vinyl overlap liner, and the integrated thru-wall skimmer.

Unboxing the 473-pound package for our In The Swim Oasis pool review was an event in itself. The kit is well-packaged to prevent damage during shipping. Here is exactly what you get inside the box:
First impressions in this In The Swim Oasis pool review centered on the sturdy feel of the steel components. The wall is heavy and well-coated, and the hardware feels robust. There were no missing parts in our kit. Remember, a pump, filter, and ladder are not included. If you are starting from scratch, you will need to factor those costs into your budget.

Setting up this pool requires some DIY skills. In our In The Swim Oasis pool review, we recommend having at least two strong helpers. The comprehensive is In The Swim Oasis pool worth buying value proposition heavily relies on correct installation. Here is our step-by-step guide based on our hands-on experience:
This is the most critical step. You need a perfectly level, flat surface. We used compacted sand and a ground cloth. Use a long level (8-foot or longer) and a tamper. An unlevel base will stress the wall and void the warranty. This step took us an entire afternoon, but it is essential for the longevity of your In The Swim Oasis pool review installation.
Lay out the steel wall in a circle around the prepared area. Connect the bottom track, which holds the wall in place. You will need to secure the track with stakes or pins to keep it from moving. This creates a solid foundation for the structure to sit on.
Before standing the wall up, you must install the skimmer. The wall comes with a pre-cut knockout for this. You trace the skimmer template, cut the wall material, and mount the skimmer housing with the gasket. Adding silicone caulk on the gasket is highly recommended to ensure a watertight seal. The included skimmer is a highlight of this In The Swim Oasis pool review pros cons section because of its superior filtration capabilities.
This is the heavy lifting part. Slowly walk the wall upright into the bottom track. Use bracing to hold it in place. Once the wall is up, install the top rails and uprights. This gives the pool its rigidity. Ensure all bolts are snug but not over-tightened.
Drape the overlap liner over the top rails. Start vacuuming the liner to pull it tight against the wall and floor. Simultaneously, start filling the pool with about 2 inches of water. This vacuum effect removes wrinkles. We found this process straightforward in our In The Swim Oasis pool review honest opinion. Once the liner is smooth, secure it with the provided coping strips and top caps.
Continue filling the pool to the recommended level. Attach your existing pump and filter to the skimmer and return fittings. Balance the pH, alkalinity, and chlorine levels immediately. Proper water chemistry from day one will protect your new liner and steel wall, a key takeaway from any professional In The Swim Oasis pool review.

No In The Swim Oasis pool review is complete without rigorous real-world testing. We used this pool as our primary summer swimming pool for several weeks to evaluate its performance.
We assembled the pool in a Midwestern backyard following the manual closely. We used a 1 HP sand filter pump system (owned separately) and a standard A-frame ladder. The pool was used daily by a family of four. We tracked water clarity, structural stability, and overall user satisfaction.
The steel wall is exceptionally rigid. There was zero flex or bowing, even with rough housing from the kids. The thru-wall skimmer worked wonders for keeping the surface clear of leaves and bugs, outperforming any over-the-side skimmer we have used in the past. The liner held up well to sunlight and standard chemical levels without fading or stretching unnaturally.
In The Swim claims the Oasis is durable and easy to install. We found the “easy to install” part to be relative—it is heavy and requires precise leveling. However, the “durable” claim is absolutely accurate. Our In The Swim Oasis pool review verdict is that the build quality matches the brand’s reputation for reliability. If you are asking is In The Swim Oasis pool worth buying based on performance alone, the answer is a definite yes.
Based on our extensive testing, here is a balanced look at the In The Swim Oasis pool review pros cons.
How does the Oasis stack up against the competition? In this segment of our In The Swim Oasis pool review, we compare it to two of the most popular alternatives on the market.
| Feature | In The Swim Oasis | Bestway Steel Pro Max | Intex Ultra XTR |
|---|---|---|---|
| Wall Height | 52 inches | 54 inches | 52 inches |
| Wall Material | Steel | Steel & PVC | Steel & PVC |
| Liner Included | Yes (Overlap) | Yes (Overlap) | Yes (Beaded) |
| Skimmer Included | Yes | No | Yes |
| Pump Included | No | No | Yes |
| Approx. Price | $1,399.99 | $599.99 | $899.99 |
| Best For | Replacement / Upgrade | Budget / Starter | Complete Package |
Choose the In The Swim Oasis if you already have a reliable filter pump and ladder, and your main goal is to replace a structurally failing pool. Our In The Swim Oasis pool review verdict highly recommends it for this specific use case. The build quality of the steel wall and the inclusion of the thru-wall skimmer justify the higher price tag compared to the Bestway Steel Pro Max.
If you are a first-time pool buyer with no existing equipment, the Intex Ultra XTR or a full Oasis kit (if In The Swim offers one) might be a better value proposition. The Intex kit includes a great filter pump and a beaded liner, offering a more complete out-of-the-box experience. However, the steel wall of the Oasis is generally considered sturdier than the composite steel-PVC walls of the Intex.
Defining the specific audience is a critical part of any expert In The Swim Oasis pool review.
Based on our experience in this In The Swim Oasis pool review, here are some tips to get the most out of your purchase.
Since the pool does not come with one, do not skimp on your filter pump. A sand filter is the best choice for the Oasis’s volume (approx. 6,500 gallons). It requires less maintenance than cartridge filters and provides superior water clarity.
The kit does not include a foam cove. We strongly recommend purchasing one. A cove rounds the sharp edge between the floor and the wall, protecting the liner from chafing and preventing a sharp crease. This is a cheap upgrade that extends the life of your liner by years.
Extend your swim season. Placing a solar cover on the water when the pool is not in use can raise the water temperature by 5-10 degrees. This makes the pool comfortable in early June and late September. You can find affordable solar covers and compatible heaters on Amazon.
Invest in a floating chlorine dispenser or a saltwater chlorine generator. Maintaining a consistent chlorine level is vital for preventing algae blooms and protecting the steel wall from corrosion. Consistent chemistry is the secret to a low-maintenance Oasis pool.
The included overlap liner is good, but if you want a thicker, patterned, or beaded liner, plan for a replacement in 3-4 seasons. This allows you to customize the look of your pool completely.
Learning from the mistakes of others is a key part of an honest In The Swim Oasis pool review. Here are the most common errors we identified:
Understanding the price is the final piece of the puzzle in any In The Swim Oasis pool review. The current retail price for the In The Swim Oasis 18 ft Round Above Ground Swimming Pool is $1,399.99 USD. This price reflects the kit’s focus on high-quality structural components.
Compared to other premium steel pool kits of the same size, the Oasis is competitively priced. When you factor in the quality of the included thru-wall skimmer and the robust steel gauge, the value becomes clear, especially if you already own the external equipment. It is an investment in durability.
In The Swim stands behind their product. The Oasis pool typically comes with a limited warranty covering the steel wall against rust-through and the liner against manufacturing defects. We recommend reading the specific warranty terms provided in the box. Their customer support team is highly responsive based on our interactions, adding another layer of trust to this In The Swim Oasis pool review.
After weeks of hands-on testing, our In The Swim Oasis pool review verdict is overwhelmingly positive for its target audience. The pool is built like a tank, features a fantastic skimmer system, and offers a clean, classic backyard aesthetic.
We give the In The Swim Oasis pool a solid 4.5 out of 5 stars. It loses half a star due to the lack of a pump included and the physical difficulty of installation. However, for performance and durability, it scores a perfect 5. Our In The Swim Oasis pool review honest opinion is that this is one of the best “replacement” pools on the market.
So, is In The Swim Oasis pool worth buying? Absolutely, if you are looking to replace an existing structure and want a pool that will last for many years without breaking the bank on a full package. It is a smart, targeted solution for the experienced pool owner. If this sounds like you, we highly recommend grabbing one before they sell out.
We encourage you to share your own installation experiences in the comments below!
Yes, for its specific target market. If you own a pump and filter, creating a durable backyard pool structure for this price is excellent value. The steel wall and skimmer are top-tier quality.
The Oasis has a stronger, purely steel wall compared to the composite walls of Intex and Bestway. However, Intex kits often include a pump. The Oasis is best for those replacing an old pool, while Intex is better for first-time buyers.
Steep. This is not a pop-up pool. Beginners should expect to spend a full weekend on site prep and assembly. Having a few experienced helpers is highly recommended for the wall installation.
You will need a filter pump, a ladder, and a ground cloth. We highly recommend a pool cove and a test kit. You can see our recommended accessories on the official product page for compatible add-ons.
In The Swim offers a limited warranty covering the steel wall against rust perforation. The liner is covered for manufacturing defects. Their support team is known for being helpful and responsive.
We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon’s return policy also provides an extra layer of security for your purchase.
Plan for a full weekend. One day for site preparation and leveling, and another full day for assembly and filling. Do not rush the leveling process.
No, you must remove the sod and create a compacted level base of sand, cove, or concrete. Installing directly on grass will lead to an unlevel pool and void your warranty.
