A campsite at dusk with a dead phone and a cold water bucket is the moment this choice comes down to: solar shower vs gas shower. A solar shower warms water with the sun or a heater charged from a panel, while a gas shower burns propane for hot water on demand. Campers who want a simple setup with no fuel to carry should pick the solar side, and campers who want hot water at once, in any weather, should pick gas. This comparison covers camp showers on both sides, judged on heat source, flow, weight and stated safety features.

All numbers here are manufacturer claims from the listings, not our measurements (12 November 2026).
How each side heats water
The solar side warms water with the sun or with a heater fed by a panel. The FLOAYANT shower is a black PVC tank that heats water up to 60°C (140°F) with solar energy, and the hot and cold control mixes sun-warmed water with cool hose water. The GRKDNSIA kit takes a different route: a 1500W immersion heater warms water in the 5-gallon bucket, stops automatically at approximately 160°F, and has dry-heating protection, while a USB solar panel charges the 6000mAh pump battery. The gas side burns propane instead. The CAMPLUX heater delivers 1.58 GPM at 41,000 BTU, with ECO and FULL gas modes and an LED temperature display. The beduan adapter heats nothing, since it is a pipe fitting with no heater at all.
Flow and water supply
Flow is stated clearly on the gas side only. The CAMPLUX lists a continuous flow of 1.58 GPM, connects to a standard garden hose and a 20 lb propane tank, and ignites at a minimum of 3.0 PSI, so it also works with 12V water pumps or gravity systems per the listing. The GRKDNSIA kit moves water with its pump in high and low flow modes through a 6.56-foot hose, drawing from the 5-gallon bucket. The FLOAYANT shower takes water from a hose and mixes it with sun-warmed tank water, but the listing states no flow figure. The beduan adapter moves no water as a shower, since it only joins pipes.
Weight and what to carry
Weight is stated for the gas heater only. The CAMPLUX weighs 13 lb and has a foldable handle, but it also needs a 20 lb propane tank and 2 D cell batteries, so the carried load is the heater plus the tank. The GRKDNSIA kit states no weight, and its 11 pieces include a tent, a bucket, a heater, a pump and a solar panel, so it packs as a kit rather than a single item. The FLOAYANT shower states no weight, and the beduan adapter states no weight either. When a listing leaves weight unstated, the article cannot call one side lighter.
What the listings leave unclear
The FLOAYANT listing disagrees with itself on capacity: the title says 5.3 GAL, the bullets say 4.3 GAL, and the spec table gives 20L/5.3GAL. The beduan listing is a pipe fitting adapter, not a shower, so it answers no shower question at all. The GRKDNSIA kit states no weight and no warranty term, and the FLOAYANT listing states no warranty term either. Only the CAMPLUX states a warranty, a 1-year limited warranty, and only the CAMPLUX states a safety certification, CSA certified with 6-in-1 protection.

Detailed Review
The listing states a freestanding solar heated outdoor shower with a black PVC tank, a 360-degree swivel head, a handheld shower and a foot faucet, heating water up to 60°C (140°F) with no electricity cost stated. The listing disagrees with itself on capacity: the title says 5.3 GAL, the bullets say 4.3 GAL, and the spec table gives 20L/5.3GAL, so the capacity is unclear until the seller confirms it. The hot and cold control mixes sun-warmed and cool hose water.
Who it's for: pool, patio and yard owners who want a freestanding sun-heated shower with a hose supply. Who should skip it: anyone who needs a stated capacity they can rely on, or a shower for a site with no sun and no hose.

Detailed Review
The listing states a 5-pack of 304 stainless steel 1/2 inch NPT adapter fittings for connecting pipes, with a stated temperature range from -868 to 1472 degrees F and a maximum working pressure of 2800 PSI. It is listed on the gas shower side, but it is a pipe fitting, not a shower: it has no shower head, no heater, no pump and no tank. It fits air, water, fuel and gas pipe systems per the listing, which is why it appears here, but it cannot shower anyone.
Who it's for: anyone who needs a 1/2 inch stainless pipe adapter for a gas or water line. Who should skip it: anyone shopping for a shower, since this listing showers nothing.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For camp showers, safety means stated shut-off protection, certifications or dry-heating protection: the CAMPLUX states CSA certification with 6-in-1 protection, and the GRKDNSIA states auto shut-off and dry-heating protection. Only the CAMPLUX states a warranty term, a 1-year limited warranty. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| CAMPLUX BW158G Tankless Heater | 9.6 | 30 | 21 | 20 | 8 | 1 |
| GRKDNSIA 11-Pc Shower Kit | 9.6 | 29 | 20 | 21 | 7 | 0 |
| FLOAYANT Solar Tank Shower | 9.3 | 26 | 19 | 19 | 0 | 0 |
| Beduan NPT Pipe Adapter | 9.2 | 9 | 15 | 10 | 0 | 0 |
Scores start at 9.2 for the lowest totals and top out at 9.8. In between, a kit’s position follows its weighted points one to one in order.
How to choose the best solar shower vs gas shower
Choose the solar side if the site has sun and a hose supply and the shower can wait for the tank to warm, and choose the GRKDNSIA kit if a tent and a heater matter more than a freestanding tank. Choose gas if hot water must flow at once: the CAMPLUX delivers 1.58 GPM at 41,000 BTU from a garden hose and a 20 lb propane tank. The beduan adapter fits no side of this choice, since it is a pipe fitting, not a shower.
| If you need | Look at |
|---|---|
| Hot water at once | CAMPLUX BW158G Tankless Heater, 1.58 GPM, 41,000 BTU |
| Sun heated water, no fuel | FLOAYANT Solar Tank Shower, up to 60°C (140°F) |
| Tent, heat and shower in one kit | GRKDNSIA 11-Pc Shower Kit, 1500W heater, 6000mAh pump |
| A pipe fitting, not a shower | Beduan NPT Pipe Adapter, 304 stainless steel |
Sizing Notes
- Match the heater to the power source: the GRKDNSIA immersion heater is 1500W and needs a compatible power source, while the FLOAYANT tank needs sun and a hose supply.
- Match the water supply: the CAMPLUX needs a garden hose and a 20 lb propane tank, and ignites at a minimum of 3.0 PSI.
- Check the capacity the listing states: the GRKDNSIA bucket holds 5 gallons, and the FLOAYANT title and bullets disagree on 5.3 GAL and 4.3 GAL.
- Keep the immersion heater submerged while it is connected to power, as the GRKDNSIA listing states.
- Match the shower to the site: the FLOAYANT shower is freestanding for pool, patio and yard use per the listing.
FAQ: power away from the grid
Which side gives hot water faster?
Gas. The CAMPLUX delivers instant hot water at 1.58 GPM from propane, while the FLOAYANT tank warms with the sun and the GRKDNSIA heater warms a 5-gallon bucket.
Can a solar shower work without sun?
The FLOAYANT tank heats with the sun, so it needs sunlight. The GRKDNSIA kit adds a 1500W immersion heater and a USB solar panel, but the heater needs a compatible power source.
What does the gas shower need to run?
The CAMPLUX needs a garden hose, a 20 lb propane tank and 2 D cell batteries, and it ignites at a minimum of 3.0 PSI water pressure.
Is the beduan adapter a shower?
No. It is a 5-pack of 304 stainless steel pipe fitting adapters for air, water, fuel and gas lines. It has no shower head, heater, pump or tank.
Which shower has a warranty?
Only the CAMPLUX states one, a 1-year limited warranty. The GRKDNSIA, FLOAYANT and beduan listings state no warranty term.
