With tap water at around \u20ac2 per m\u00b3 on average in Spain, filling it usually costs less than \u20ac30. Here are the litres, the cost and the filling time for each size, and how to work it out for your case.<\/p>\n<h2>How much water does an above ground pool hold?<\/h2>\n<p>It depends on the size and the depth. To work it out yourself, one formula is enough:<\/p>\n<ul>\n<li><strong>Rectangular<\/strong>: length \u00d7 width \u00d7 water depth. A 4 \u00d7 2 m pool with 1.10 m of water holds 8.8 m\u00b3.<\/li>\n<li><strong>Round<\/strong>: 3.14 \u00d7 radius \u00d7 radius \u00d7 water depth. A pool 4 m across (2 m radius) with 1.20 m of water holds about 15 m\u00b3.<\/li>\n<\/ul>\n<p>Each m\u00b3 is 1,000 litres. Bear in mind that a pool is never filled to the brim: you normally leave a few centimetres free, so the real volume is a little below the maximum.<\/p>\n<h2>Litres, cost and filling time by model<\/h2>\n<table class=\"hl-compare\">\n<thead>\n<tr>\n<th>Model<\/th>\n<th>Water<\/th>\n<th>Hours with one hose<\/th>\n<th>Cost at \u20ac2\/m\u00b3<\/th>\n<th>Cost at \u20ac4\/m\u00b3<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Azora XS (\u00d82 m)<\/td>\n<td>1.5 m\u00b3<\/td>\n<td>1.5 h<\/td>\n<td>3 \u20ac<\/td>\n<td>6 \u20ac<\/td>\n<\/tr>\n<tr>\n<td>Azora S (\u00d83 m)<\/td>\n<td>5\u20138 m\u00b3<\/td>\n<td>5\u20138 h<\/td>\n<td>\u20ac10\u201316<\/td>\n<td>\u20ac20\u201332<\/td>\n<\/tr>\n<tr>\n<td>Azora M (\u00d84 m)<\/td>\n<td>9\u201315 m\u00b3<\/td>\n<td>9\u201315 h<\/td>\n<td>\u20ac18\u201330<\/td>\n<td>\u20ac36\u201360<\/td>\n<\/tr>\n<tr>\n<td>Azora L (\u00d85 m)<\/td>\n<td>15\u201328 m\u00b3<\/td>\n<td>15\u201328 h<\/td>\n<td>\u20ac30\u201356<\/td>\n<td>\u20ac60\u2013112<\/td>\n<\/tr>\n<tr>\n<td>Azora XL (\u00d86 m)<\/td>\n<td>40 m\u00b3<\/td>\n<td>40 h<\/td>\n<td>80 \u20ac<\/td>\n<td>160 \u20ac<\/td>\n<\/tr>\n<tr>\n<td>Marea XS (200\u00d7200 cm)<\/td>\n<td>3 m\u00b3<\/td>\n<td>3 h<\/td>\n<td>6 \u20ac<\/td>\n<td>12 \u20ac<\/td>\n<\/tr>\n<tr>\n<td>Marea S (300\u00d7200 cm)<\/td>\n<td>5 m\u00b3<\/td>\n<td>5 h<\/td>\n<td>10 \u20ac<\/td>\n<td>20 \u20ac<\/td>\n<\/tr>\n<tr>\n<td>Marea M (400\u00d7200 cm)<\/td>\n<td>9 m\u00b3<\/td>\n<td>9 h<\/td>\n<td>18 \u20ac<\/td>\n<td>36 \u20ac<\/td>\n<\/tr>\n<tr>\n<td>Marea L (400\u00d7300 cm)<\/td>\n<td>18 m\u00b3<\/td>\n<td>18 h<\/td>\n<td>36 \u20ac<\/td>\n<td>72 \u20ac<\/td>\n<\/tr>\n<tr>\n<td>Marea XL (500\u00d7300 cm)<\/td>\n<td>22 m\u00b3<\/td>\n<td>22 h<\/td>\n<td>44 \u20ac<\/td>\n<td>88 \u20ac<\/td>\n<\/tr>\n<tr>\n<td>Marea XXL (600\u00d7300 cm)<\/td>\n<td>27 m\u00b3<\/td>\n<td>27 h<\/td>\n<td>54 \u20ac<\/td>\n<td>108 \u20ac<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Azora S, M and L come in two heights: the first figure is for the low version and the second for the high one. Volumes are approximate with the pool full.<\/p>\n<h2>How much does it cost to fill with tap water?<\/h2>\n<p>The average price of household water in Spain is around \u20ac2 per m\u00b3, including supply and sewerage, according to the AEAS tariff study. In France it is close to \u20ac4 per m\u00b3. But the average says little: prices vary a lot from one municipality to another, and most tariffs are <strong>tiered<\/strong>, so the cubic metres above a certain consumption cost more.<\/p>\n<p>To know your real cost, check your last bill: find the price of the highest tier and multiply it by the m\u00b3 of your pool. If you fill it in the same billing period as a high-consumption month, the bill may rise more than the table says.<\/p>\n<p>Before filling, also check whether your local council has restrictions. During droughts, some municipalities limit or ban filling pools with mains water.<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/10\/piscina-desmontable-redonda-azora-s-3m-terraza-vistas-mar.webp\" alt=\"Helyora Azora S 3 m round above ground pool full of water on a terrace with sea views at sunset\" style=\"border-radius:12px;max-width:100%;height:auto\" width=\"1200\" height=\"1600\"><\/figure>\n<h2>How long does it take to fill?<\/h2>\n<p>A household garden hose delivers between 15 and 20 litres per minute, so it fills roughly 1 m\u00b3 per hour. A 9 m\u00b3 Marea M takes about 9 hours and a 40 m\u00b3 Azora XL almost two days.<\/p>\n<p>To speed it up, use two hoses from different taps or start at night. But don\u2019t leave it filling unattended for hours: halfway through, check that the floor has settled properly and that the water is rising evenly on all sides.<\/p>\n<h2>Is a tanker truck or well water worth it?<\/h2>\n<p>A <strong>water tanker truck<\/strong> fills the pool in minutes, but it is much more expensive: filling a 10 m\u00b3 pool costs around \u20ac300, compared with \u20ac20\u201340 with tap water. It only pays off if there are water restrictions, if your supply is very slow or if the pool is very large and you are in a hurry.<\/p>\n<p>A <strong>well water<\/strong> is almost free, but it is worth testing first: if it contains iron, manganese or a lot of limescale, it can turn brown or greenish when you add chlorine and stain the PVC. A basic test at a pool shop will tell you whether it needs treating.<\/p>\n<h2>How often do you need to change the water?<\/h2>\n<p>With a filter pump and chlorine and pH at the right levels, you don\u2019t need to change it during the season. Normally you fill it once at the start of summer and only top up what is lost to evaporation and splashing, a little over half a centimetre a day in midsummer. A cover when you are not using it greatly reduces that loss. We explain the full routine in <a href=\"\/en\/maintenance-of-a-portable-pool\/\">maintaining a portable pool<\/a>.<\/p>\n<h2>How much does a full pool weigh?<\/h2>\n<p>The same as its water: each m\u00b3 weighs one tonne. A full Marea M weighs about 9 tonnes and an Azora XL about 40. That is why the ground matters so much. You will find all the details in <a href=\"\/en\/what-to-put-under-above-ground-pool\/\">what to put under an above ground pool<\/a>.<\/p>\n<h2>In summary<\/h2>\n<p>A family above ground pool holds between 5 and 15 m\u00b3, fills in an afternoon or a night with a hose and costs between \u20ac10 and \u20ac30 of water in most Spanish municipalities. Fill it once a season, keep the water clean with the filter pump and top up what evaporates.
