How to Choose the Right River Tube
Choosing a river tube is mostly about matching the tube to how you float. Here's how we think about size, weight capacity, and what separates a tube built to last.
What Size River Tube Do You Need?
Two things point you to the right size: how many people are floating, and how much weight the tube needs to carry. If you're floating on your own, our Siesta Float 48" holds up to 300 lbs and gives you room to settle in with a drink and a backrest. If you want extra space to stretch out solo, or you're bringing someone along, our Siesta Float Double 90" steps up to 600 lbs across two seats.
River tube sizing, by how you float
| How you paddle | Board length | Why it works |
|---|---|---|
| Solo floating on the river, lake, or pool | Siesta Float 48", 48" inflated diameter | Steady and easy to settle into, with a backrest and 300 lb capacity. |
| Floating with a partner | Siesta Float Double 90", 90" inflated length | Two seats and a wraparound grab rope, holding up to 600 lbs |
| Keeping drinks cold on the water | Siesta Float Double 90" | A built-in center cooler sits between the two seats |

What Makes a Quality River Tube
It depends on the model. Our Siesta Float 48" holds up to 300 lbs, and our Siesta Float Double 90" holds up to 600 lbs across two riders. We build both from 18-gauge puncture-resistant vinyl for calm flatwater. Add up your body weight plus anything riding along with you, and leave a little room so the tube still floats high and steady.

Setting Up and Caring for Your River Tube
The best part of an inflatable is how little fuss it takes. Here's the whole routine we'd follow, from your first breath into the valve to long-term storage.
How to Inflate and Deflate Your Tube
Both our Siesta Float tubes use an easy-inflate anti-leak screw valve, so you won't need a pump. Breathe in deep and exhale slowly and steadily into the valve rather than in quick, shallow bursts, then seal it up once the tube feels firm with a little give. We recommend about 0.44 PSI for the Siesta Float 48", so it doesn't take much air to get going. Want to speed things up? Our electric pump handles inflation and deflation with ease.
How Long Do River Tubes Last?
With the right care, a well-made river tube lasts several summers. Rinse it with fresh water after every float, especially if it's exposed to silt, sand, or salt. Store it in a cool, dry spot out of direct sun, and keep it only lightly inflated in storage to ease stress on the seams. Skip dragging it across concrete, gravel, or rough ground.
Cleaning, Storage, and Repair
Rinse your tube with fresh water after every float, especially after silty, sandy, or saltwater days, and let it dry completely before packing it away. Store it lightly inflated or loosely rolled in a cool, dry spot out of direct sun to ease stress on the seams. If you pick up a small puncture, we've got you covered: our Siesta Float 48" includes a repair kit, and our Siesta Float Double 90" includes two repair patches.
FLOAT EASY
River Tube Safety and What to Wear
Safety first. Float in calm, protected water away from strong currents and boat traffic, wear water shoes for rocky entry and exit points, and check your local rules before you head out.
River Tube FAQs
What is a river tube?
A river tube is an inflatable float made for drifting on calm, slow-moving water like lazy rivers, mellow creeks, and flatwater stretches where you let the current do the work. You sit inside and relax while it carries you along. We build our retrospec Siesta Float river tubes to work in lakes and pools too, so you get a versatile river float for anywhere the water stays calm and protected.
What is the best river tube for floating?
The best river tube keeps you comfortable for hours, not just the first stretch of the river. We'd look for a built-in backrest, mesh bottom, cup holders, and sturdy handles. Our retrospec Siesta Float 48" covers all of that for solo floaters, and if you're heading out with a partner, our Siesta Float Double 90" gives you two seats, a built-in cooler, and a wraparound grab rope to keep you both connected.
What should you look for when buying a river tube?
We'd start with material quality, then features. Puncture-resistant vinyl holds up better on rivers with rocky bottoms or sandy banks. A backrest makes long floats more comfortable, a mesh bottom keeps you cool, and sturdy grab handles give you something to hold when the current picks up. Floating as a couple or group? A double adds a cooler and more shared space. Our retrospec Siesta Float lineup covers single and double options with all of that built in.
Are inflatable river tubes worth it?
We think so, especially if you want easy summers on the water without the storage headache. Our retrospec river tubes pack down small, inflate in minutes, and cost a fraction of bigger water gear, so they're an easy yes for lazy river days, lake afternoons, and pool hangs. If you need a permanent setup for rough water or heavy loads, that's a different kind of gear, but for relaxed flatwater floating, a good river tube is hard to beat.
What are river floats made of?
Most quality river floats are made from vinyl or PVC for puncture resistance, flexibility, and durability in sun and water. We make our retrospec Siesta Float Double from 18-gauge puncture-resistant vinyl, built to hold up across repeat summers on rivers, lakes, and pools. Heavier gauge vinyl means better protection against scuffs, scrapes, and the occasional sharp surface on the riverbed.
How much weight can a river tube hold?
It depends on the model. Our retrospec Siesta Float 48" holds up to 300 lbs, and our Siesta Float Double 90" holds up to 600 lbs across two riders. We build both from 18-gauge puncture-resistant vinyl for calm flatwater. If you want extra room to float solo, the Double's 600 lb capacity gives you plenty of space to stretch out.
Can two people use one river tube?
Yes, as long as you pick the right one. We built our retrospec Siesta Float Double 90" as a two-person river tube for floating with a partner. It has two seating areas, a built-in center cooler, two cup holders, a mesh bottom, and a wraparound grab rope that keeps both of you connected and comfortable all day. Our Siesta Float 48" is our single-rider tube.
What is the difference between a single and double river tube?
Our single river tube, the retrospec Siesta Float 48", is sized for one rider, holds up to 300 lbs, and runs $39.99. Our double, the Siesta Float Double 90", is wider and longer, holds up to 600 lbs across two riders, and adds a built-in center cooler and wraparound grab rope for $69.99. If you're planning to float with a partner, we'd go with the double.
How do you inflate a river tube?
Our retrospec Siesta Float river tubes use an easy-inflate anti-leak screw valve, so you won't need a pump. Breathe in deep and exhale slowly and steadily into the valve rather than in quick, shallow bursts, then seal it up once the tube feels firm with a little give. We recommend about 0.44 PSI for the Siesta Float 48", so it doesn't take much air. Want to move faster? Our electric pump makes quick work of it.
How do you patch or repair a river tube?
You can fix small punctures with a vinyl patch kit. Dry the area around the hole completely, apply patch adhesive, and press the patch down firmly for several minutes. Let it cure fully before you re-inflate. We set both models up for this: our retrospec Siesta Float 48" includes a repair kit, and our Siesta Float Double 90" includes two repair patches. We'd check your tube for slow leaks before and after each float, especially after rocky rivers.
How long do inflatable river tubes last?
With the right care, a well-made river tube lasts several summers. Rinse it with fresh water after every float, especially after silt, sand, or salt. Store it in a cool, dry spot out of direct sun, and keep it only lightly inflated in storage to ease stress on the seams. Skip dragging it across concrete, gravel, or rough ground. Treat it that way and our retrospec Siesta Float tubes will be a long-term part of your summers.
How do you store a river tube?
We'd store your river tube the way we store any inflatable water gear: either lightly inflated or fully deflated and loosely rolled, never packed away tight or wet. Keep it dry and somewhere cool, out of direct sun, since heat and UV break down vinyl over time, and trapped moisture invites mold. A quick rinse and a full dry before storage keep your retrospec Siesta Float ready for the next sunny day.
Can you use a river tube in a lake or pool?
Yes, and it's one of our favorite ways to float when a river isn't handy. We built our retrospec Siesta Float 48" and Siesta Float Double 90" to work in calm lakes, backyard pools, and any flatwater away from boat traffic and strong currents. A calm lake or pool is also a great place to break in a new tube and get comfortable before your first river float of the season.
What is the difference between river tubing and river rafting?
River tubing means drifting on calm, slow-moving water in an individual tube, letting the current do most of the work. River rafting uses a larger, multi-person raft and paddles to navigate faster or rougher water, including whitewater. Tubing is laid-back by nature, while rafting takes more active effort and suits rivers with technical sections or rapids. We design our retrospec Siesta Float river tubes for tubing on calm flatwater, not whitewater runs.
What accessories come with a retrospec river tube?
Both our retrospec Siesta Float models arrive ready to float. Our Siesta Float 48" comes with a built-in backrest, mesh bottom, two cup holders, a wraparound grab rope, two heavy-duty handles, and a repair kit. Our Siesta Float Double 90" adds a built-in center cooler and two repair patches, along with the same grab rope, handles, backrest, and mesh bottom for two riders side by side.
